What to do with my G1 thats not being used?

So, I've gone out and bought the MyTouch 3g Slide, and most likely won't be going back to use my G1 as my daily driver. I have no plans to sell the G1, well, not yet anyways.
So what can be done with my G1? I was thinking of maybe using it as a navigation-only device. Problem is, with no SIM, I of course would need a nav system that stores the maps on the SD card. The phone is rooted, so I was wondering whats the best way to try and trim this phone down to almost nothing, so that all it will basically be able to do is load the nav app I install. Is this possible or already done?
I really liked this device. It did pop my Android cherry after all, and I don't just want it to collect dust.
Thanks in advance.
Edit: I intentionally posted this in General, but after re-reading this, would it make more sense to post this in the Development forum? Can a mod move it if so...?

put it in a box and ship it to me this way your not selling it.... your giving it away

yeah... send it my way. My kid has been ogling my G1 forever now. He wants one soooo bad. LOL.

OK, aside from selling it, or giving it away, what else...

I've often thought of what to do with my G1 when and if a successor becomes available.
I personally would love it if some developers could get together to make a rom that would resemble what the Ipod Touch is to the Iphone. All the programs and games, no phone bits. Just use it as a personal media player. Or in my case, i use it as a wifi remote for my HTPC also.
Oh, and does it make you wonder..when 2.2 source is available to the public, would trimming out all the telephone parts make the G1(with dangerspl) upgradeable again?

Cancel your home landline, put google voice on the g1, keep it connected to wi-fi all the time, and you got free nation wide calling and a cheap international calling. Also since it is connected to wi-fi, you can still use it as a phone.

Send it to me pretty please (I need to update my N95).
... Okay fine, how about charity?
LOL ...no?
Well aside from using it as:
a second phone,
Digital camera (poor one),
PMP/iPod (listen to music/watch pictures/videos),
Portable gaming console (Atari, C64, Sega Genesis, GBA, SNES and Android games),
Home entertainment unit (surf on your couch with wifi) and
eBook reader (nonetheless poorly).
I can't think of anything else.
If you can't find another use for it besides just a mobile phone, you're really missing out and should just post it to me

Definitly new ipod or home phone

there's a pretty nifty howto over at instructables.com on using the G1 to power a home-made robot

I have mine on wifi and setup like this.. pretty cool as I now can use it as separate phone while at work, home etc .. and with the app penetrate I get even more use of the wifi

Ya know, I am planning on upgrading to the Touch Slide or whatever in a few months when I can afford it...when I do, I might just whip something up ROM wise that has no phone bits, but strictly media apps like:
WIFI Remote for various HTPC frontends (XBMC, MediaPortal, etc)
Music Apps (stock music, 3, etc)
Anything else I can think of
I think that would be a fun project. And considering everything in my home is OpenSource, it shouldn't be all that hard to find (or create) all the apps I need.

That sir, would be pimp.
But to cut down the rom size why not make those a flashable addon? Make it so they install to sd automatically maybe? The biggest thing would be to fit 2.2 on the phone, with support for apps to sd, jit, and all the other delicious froyo goodness.
Thanks for listening.

Use it as a dedicated SIP phone in wifi areas.
First get a google voice number and a gizmo5 sip number.
Forward your GV number to your regular cell number as well as your gizmo5 sip number using sipdroid (market) on the G1, so that when you're in wifi areas both your cell and your g1 will ring. Now you can answer either based on whatever... caller, importance, etc.
Make outgoing calls in wifi using all of the above and the GV callback program (market) so as to make totally free calls. Add some money to google voice for international.
Use it on the tabletop like a pda and take calls on your cell. actually very convenient. I've got a clamshell which I prefer for talking and can take more abuse than the G1.
Get a Tmobile $100 prepaid sim which is good for a year. That's 10c min and your own number for a year! ..and if you add any money to it the expiration is extended to a year from the add. At that price you can throw it in the car for 11 months and forget about it only to switch it to another phone later.

i have a retired htc magician which i am using as an alarm clock and listening to audio books. It served me well over the years. Was my first HTC phone. Battery still lasts more than a week...

Vibrant and NO data plan but 3G/E signal?

My wife fone does not subscribe to data plan. But sometimes, she got 3G/E signal display on the phone. Will Tmobile automatically add data plan to her phone? is she getting charged to browse the internet? Is there a way to disable this? Thanks.

How did she get a plan without data? Its a requirement for the android devices.
I'm sure tmobile will automatically add it.
Yes they will charge. Either 30 bucks a month for per meg. I had someone that tried to do this with Verizon and he got a bill for 300 bucks.
You can turn sync off which will prevent it from going online to get info. (sometimes)

Those 3G/E are normal even if you dont have data plan
Disable with "APNdroid" from the market. After you disable 3G/Edge/Gprs data connection make sure you reboot so it actually disables it...you will no longer see 3G/E BTW Expect even better battery life after doing so.

I wouldn't touch sync its still very useful even if just using Wifi

Not sure what you will get charged but a data plan is NOT required on this phone. On other android devices it has been but for some reason this one can be used as a "dumb" phone. Store employees may tell you otherwise so they can get the commission.

I've seen people INSIST up and down that you can't run smartphones without a data plan or the carrier will add them. They told me the same thing about AT&T and guess what? My wife runs her iphone 2g without one (edge disabled) and nary a problem.

I used my nexus and then my vibrant as prepaid with no problems...I went into the store and paid full price for vibrant and told them i had a tmobile prepaid sim card i was going to use...they dont care.
But now i have a $60 month plan so i can use my smart phone for what its intended for

yep, no problem with my even more + plan sans data. been using it that way since i got my g1, and they have not said anything.

thats not true. its not required to have a data plan with an android phone. I talked to a tmobile rep and he said if you buy the android from them by either upgrading or starting a service then you do. but if you bring a tmobile android to them to start up service you dont have to have a data plan. although its really pointless to have an android phone without a data plan.

thanks for the replies guys. I download APN Droid and that took care of the concern. Thanks.

you dont need to download any apps. just go to mobile network, select APN setting and change the epc.tmobile.com to some arbitrary characters like "24532lk34j23l45ju204213" and hit the "menu" button and save. then turn off background sync at all time (unless you turn on wifi for android market donwload apps and gmail or apps that requires internet) and then reboot the phone.
the phone will will still shows 3G/E but u wont be able to get on internet as the APN setting has changed. T-mobile wont charge you data plan for this even though they got the IMEI detected. Ciao!

Yea remove epc.tmobile.com and for some reason you want it back but you forgot what it was so you go searching online because your forgot to write it down...you get the point
You really think that's easier than just getting APNdroid click to disable, click to enable. And why would he want to and disable background sync im sure he will use wifi.
BTW when you use your "method" and still see 3G/E your phone might not be able to connect to tmobile but it is still searching for those signals ultimately wasting battery

I don't have a data plan and I haven't disabled the APN settings. Whenever I go onto the browser without WiFi it shows me a T-Mobile page that just says that I need a data plan use the internet. It has never charged me. But I do have an unlimited text message plan and I can send picture messages just fine. Just an FYI.

I have used several android phones with out a data plan. We have a family plan, and so all I needed to do was use the sim card for a line that did not have a plan. It actually works well, and were I not waiting for the ota for froyo, I would be tempted to drop my data plan and I use my phone extensively.
If I recall correctly, the only applications that I could not use when out and about were the browser based apps. Initially, the thought of not being able to user google maps would have been enough of a reason not to drop the data plan, but with my trip to canada, that was cured with a $20 download of Co pilot. I am generally using my phone where I have wifi access. Nonetheless, I still was able to get email updates with out a data plan.
In essence, with out a data plan you can still access email, messaging, and use many if not most of your downloaded applications. If you need constant access to FB, you tube, twitter and the likes, you will not easily be able to drop you data line.
Note that I was able to get my wife's phone upgraded to a my touch slide on t-mobile and was not required to add a data plan. I did, but it was weeks after I already had it up and running which was possible because it provided an option to configure wifi before having to have the google account configured (unlike the G1).
Just fyi those those interested.

T-Mobile will NEVER add a data plan to your line, especially without your knowledge.
I've been using a smartphone with my plan without data for years now.

Slow data speed

Hi everyone, im running typhoon cm7 v3.0.0 and i was wonderin if there is a hack to make tmobile believe we are using less data than we really are? I hate it once i hit 5gb downloaded data my data connectuion speed slows down drastically and i hate it!!! So if anyone knows a solution plz help.....

i disagree
there are some really effective tricks that can be used to Significantly reduce your data usage on android. i use data a lot on my phone and i never hit 100MB data usage. how in the hell you are able to hit 5GB? anyway try the following tricks:
1. use "Droidwall"to only allow certain importantapps to access the the 3G connection. the less important apps can run or update just fine from WIFI
2. use "adblock" this will block connection to all ad servers
3. only allow opera mini and Operamobile w/Turbo enabled from droidwall to save data. if you want to use another browser (cant really see why) use them when you are on WIFI.
4. avoid push mail if you can. it will kill your battery and may end up eating your data plan to some extent.
5. use "3G watchdog" or something similar and place a widget in the homescreen to constantly remind you of the current data usage.

Well I have not really done any looking for it, but there was suppose to have been a work around of some kind to still be able to get 3G and 4G speeds after you were throttled. But I also heard T-Mobile has already found out about it and fixed whatever glitch was in the system. You can do some digging if you want, bit it might be in vain when or if you find it.
Now don't get me wrong I think if they say unlimited it should mean unlimited, but I am not going to get into all of that as it as been beatin to death. But if you are going over 5Gig every month I want to know what the heck you are doing too cause until almost two weeks ago when I accidently busted my laptop screen. I tethered my HD2 via WiFi like for like 14 to 16 hours a day and only got up to 3.5 gig once. You might seriously want to think about a home internet set up or start using some local WiFi hotspots more. Heck I know a guy that goes to the local Hardee's and sets for 6 to 8 hours a day just to use their WiFi for free. I have set there for 4 hours befor. r,

Thanks for all ur replys........me personally am a huge fan of call of.duty...and i play online most of the time....tethering my phone is excellent thats why i use it......i heard a hack about one of the droid phones on verizon that did this sort of thing so i thought it wud be possible on my hd2.......

Just Bought The LG Quantum on Ebay

Hi all,
I just bought a used LG Quantum from ebay. I would greatly appreciate all of your input to help me verify that this phone is working properly. I am upgrading from a Touch Pro 2, wm 6.5.
1. I don't see a water indicator sticker. Is there a blue sticker in the battery compartment to indicate water? I see a small hole that is white filled on the top left region, opposite the sim. Is this it?
2. How can I verify if the ROM is stock? Is there anyway for me to check to see if the previous owner has replaced the ROM or has done anything to the phone that might prevent the Mango update? Mango update is REALLY important, I have been holding off upgrading until Mango comes out.
3. I have been using the Touch Pro 2 without a data plan. I don't have a contract and don't want to enter a contract. All my datat usage is wifi, and it has served me well. I have wifi at the office, and wifi at home, therefore no need for a 3g data. In WM 6.5, I can turn off the 3g data modem. Can I do the same with this LG? I also have AT&T block data on their side, but I don't want any "accidental" data charges. I would feel much better if I can turn 3g off on my end.
4. How do I do a factory wipe? This might be necessary if the previous owner have not done so. It is currently charging so I haven't got the chance to mess with it. Its very hard waiting....
I might have more question as I go along. Thanks in advanced for everyone's help. I really love Windows Mobile and have been using Windows Mobile phone before the iPhone ever came out. I got my wife an Android phone, and I'm very disappointed with Android. I can't believe companies putting out Android phones that are not usable out of the box. You have dig for apps and install additional apps in order to make the phone acceptable for use. Anyway...thanks again everyone.

Update:
Well, I found the factory reset in the Setting menu, and have done it. I noticed that after resetting the phone, I went through the setup, and saw that in the setup process there was a check box for data option. I unchecked the box so that the phone would not use data. Does anyone know if that would stop any 3g data access?

Update:
It looks like no one wants to share their experiences, so I'll just go on with this monologue and post things as I find them.
I found the 3g data switch in the setting menu. So it looks like you can turn off 3g data and just use wifi.

Hey, I just got this phone as well. Local bell was clearing them out for 78.83. looks to be pretty cool. Just bought it as an extra phone. I don't think its anyone is ignoring you, this is just a low profile device haha. I've just updated it to Mango as well. Runs really well.

I've just connected my phone to the zune software for update to Mango, but it says the phone is up to date: 7.0 (7390).

I got impatient so I did the disconnect from the internet trick. Was a breeze and worked right away and I've had no problems with it.

Can someone verify for me if this is stock rom:
OS Version: 7.0.7390.0
Firmware Revision Number: 1.1.3.11
Hardware Revision Number: 1.1.0.0
Radio Software Version: 1.1.3.11
Radio Hardware version: 0.3.5.0
Bootloader Verson: 1.5.1.0
Chip SOC version: 0.30.2.0
I want to know if the NODO version is official or the beta.

Update:
ok guys, the windows phone gods have looked down and seen how I'm searching and poking around trying to verify my phone OS so that I can update to Mango; and they are smiling on me. Out of the blue today, the zune software said I have an update! Woohoo! Mango is coming, its been updating for 30 minutes now.

Update:
Now running Mango and loving it!
Does anyone know where the water indicator sticker is located on this phone?

Great to hear... I'm still waiting on mine. Trying to be patient.

You were right, the water indicator is the little hole that should be white when dry, and turns pink after getting wet. There's another, larger, square indicator on one end of the battery.

Otnos. I just bought mine as well on Ebay. Been waiting a long time to upgrade from my HTC Tilt to the new OS. I have to wait for mine to show up, but your rambling postings are great reading as i would ask similar questions being new to the WP7.5 world.

hahaha...Good to have you chime in. I'm liking WP more an more each day. AT&T recognized this phone and automatically listed it on my online account. I love thr fact that I can turn off data, in the Settings, Cellular page. I use wifi instead.
At first I was afraid that wifi would drain my battery fast, so I manually turn it off and on. But I have been reading and found that WP will turn of wifi when the screen is off, isn't that great? Now I just leave wifi on, and whenever I turn my phone on, it automatically have a data connection.
I don't use text either. Why pay AT&T $20 a month for this funtion!
Here is my work around. I use Google Voice. Set Google Voice to send text to your Hotmail account that you associated with your phone. When someone text to your Google Voice number, it INSTANTLY goes to your Hotmail. Your Windows Phone will receive a notification in the email live tile. You tap on the email tile to read the text and then reply by email. When you reply to that mail on your phone, your receipient will receive a TEXT reply. Voila! Free text.

lol...after describing in details how I can get free texting, I just discovered AT&T Go Phone (pre-paid plan) that has unlimited talk & text for just $50/month. This is a great plan for those of you in the US who have AT&T and no longer under a contract. I used to be on the $40/month plan that only gives me 450 minutes/month. Now I have switched over to their Go Phone prepaid plan that is $50/month ($55.01 with tax) and get unlimited Talk & Text! Data is also available but for additional fee.

I have a Tilt still and am curious to see what you think! I've been contemplating upgrading either to an LG Fathom, LG eXpo, or maybe a Quantum. However, the Samsung Captivate Glide was just announced, so maybe that's what I'll try... I wonder if it is worth getting a one or two year old brand new phone, when my then new Tilt has worked for over 3.5 years.

That is interesting. I have been out of my contract for some time. I am grandfathered with the $30/month unlimited data, and another $5/month for 200 texts. If I didn't travel so much, I think your option would really work. Once I change my plan though, there is no going back...

The quantum is a 1st Gen phone. If you are able, I think you should get a 2nd Gen phone instead.

So I'm probably buying one of these on ebay (I cant write on touchscreens so im in need of a smartphone android or WP with QWERTY on it).
Some questions:
-Whats the newest version of windows phone right now?
-Can LG Quantum be updated to that version?
-How's the battery on this model? Can I get 2 days with moderate use?
-Is anyone trying to make a graphic EQ to WP7? I think the lack of this basic multimedia feature is just ridiculous.
Thanks and sorry to make so much questions

WP7 newest version is Mango, and this LG Quantum can be updated to Mango. I'm running Mango right now.
The battery life is good, you can easy get 2 days moderate use.
I'm not sure I understand what you mean by graphic EQ?

Kindle 2 3G sim+cardock= awesome car enhancement?

I have a very odd set of questions to accomplish a very specific thing.
The atrix 4G was the best smartphone to use when driving, The simple mount with the unified power/audio cable, the interface, so I want to make it a permanent carphone for navigation and music.
so my roommate that I drive around with went with this idea and threw in his kindle 2 sim card to use, but there are 2 problems, but only one of them needs to be solved.
A. no data, I get signal, it recognizes the signal strength and carrier, but it can transfer any data, I believe it is a problem with the APN but after hours of researching and tweaking, I got no progress.
B. offline navigation. The sim will give me a GPS location, which is awesome, but while I can download maps of the area in google maps I cannot use navigation without a web connection. I would prefer to use the native app but that's just me being reluctant to trying new apps, so if I have to use a 3rd party app I can.
I don't really expect the kindle 2 sim to work for obvious reasons, even if I did get it to do data I would use it very lightly.
Another option is some kinda way to switch between 2 AT&T sims on my "unlimited" data account, as physically switching them will be a pain.
3rd option is a some kinda cheapo AT&T/T-Mobile quarter gig $10/mo plan.
At this point I am just tossing around ideas, and need some help steering and executing this project.

I'd be shocked if whatever network that Amazon uses for their kindles doesnt check the IMEI number of the phone to ensure its actually a kindle for this very reason. You're going to have to look at some other carrier for your needs. I'd avoid T-Mobile since the Atrix does not support their 3G bands at this time (they may in the future to support unlocked iphones, but I wouldnt count on it).

Amazon is probably using it's own proxy server for mobile data, and even if you managed to configure your phone to use it most likely Amazon will ban your sim card very soon.
I think the best solution is to set up your regular phone with unlimited data as wi-fi hotspot and use this wi-fi connection from Atrix mounted in car.

I agree with tananaev. I have read about countless people getting their kindle banned because they tried to tether it. Setting up a hotspot in your car from primary phone would be best. Just remember someone might try to break your window to steal your phone. I personally use line in with PowerAmp. Turns off when unplugged, turns on when plugged. Simple.
Data is not important for a 'car stereo'. With the atrix, you have roughly 10gb of space for music/videos and microSD are really cheap if you need more. Also, consider trying Navfree from the market. It uses openstreetmaps.org and is completely free and offline.
