ok, so i had seen on another forum a code to get into a base menu for the eris
*#*#4636#*#*
going into the phone information showed rev 0 being used when i was running 1.5, after i did the update i did it again a couple days later and saw i was now running rev a, curious about this because a. i thought the eris was supposed to have rev a to begin with, b. not sure if the update enabled it or it was just a bad signal or something, i went to a friend that had not done the update yet, checked his before update, showed rev 0, did upgrade went to rev a
i have noticed a tad increase in internet speed, dont know what all this means, just interesting i think
Mine shows Rev .A now as well... I do not remember that drop down there at the bottom for preferred network type, strange that it lets you choose GSM. I wonder if these phones actually have the capability of connecting up to the ghetto blue network?
I believe before we were connected to EVdO rev A, however since 1.5 was 'modified' to support CDMA (not native till 1.6 ironically) it just did not display correctly in field test mode.
Nice to finally know for certain though!
GSM is built into the Android source. Essentially, CDMA is a "Branch" of a GSM master. For example, after a wipe in 1.5, my phone refused to connect to Verizon's network, saying a "SIM Card is not inserted or GSM Network unavailable". Whereas the problem was my phone just wasn't reprogrammed for my account.

Right, the cdma stack is included as of 1.6
so, does that mean that we should be getting better service now? as its "native" now, or what does that mean exactly

I can confirm that on 1.5 it says rev.0.
From Wikipedia:
The EV-DO feature of CDMA2000 networks provides access to mobile devices with forward link air interface speeds of up to 2.4 Mbit/s with Rev. 0 and up to 3.1 Mbit/s with Rev. A. The reverse link rate for Rev. 0 can operate up to 153 kbit/s, while Rev. A can operate at up to 1.8 Mbit/s.

I am currently heavily using data connections over an EDGE network, and noticed something interesting.
When I set the phone band settings to Band = "Auto", I get much slower download speeds. I used the fieldtest utility to check the GPRS/E-GPRS stats, and can see that the phone was only allocating 1R1T, or 1 receive slot + 1 transmit slot! (limiting the speed to about 60kbit/sec for EDGE).
I remember I used to get better speeds, so I tried changing the band settings to Band = "GSM900/1800 + UMTS2100" which is what my network is on.
Now the download speeds were fast again! Back to the fieldtest utility and saw that the phone was now allocating 4R1T (4 receive slots + 1 transmit slot), giving me about 200kbit/sec downloads.
I wouldnt have guessed that the band settings would affect the GPRS/EDGE timeslot class usage. Note that this testing was done using radio 1.40.30.00, and WM6 LVSW 19-5 / Elf 2.1.
Found that the Band settings cause the change. The Mode (Auto/GSM/WCDMA) setting does not affect it.
UPDATE: This seems to affect only certain radio roms. On others, it has no affect (those roms can allocate 4R1T on Auto band).
Tested using EDGE on a GSM1800 network. Most likely in a 3G or HSDPA network there will be little to no affect.
Radio ROMs which are affected:
1.40.30.00, 1.38.30.00
Radio ROMs which are NOT affected (no difference):
1.41.00.10, 1.38.00.01, 1.38.00.10
If you are trying this out, please include the slot combination you got (with an active download), your radio rom version, OS version, network type (GPRS/EDGE/3G), and band (GSM850,900,1800,1900) if you know them. May try to compile some statistics and update this post.
(so far, its looking like this behaviour is limited to only the 1.xx.30.xx radio roms)
Switching settings
I sense everyone is currently changing their settings. I tried it and whether it was the placebo effect or not - sure did seem to be faster.

Settings on Auto, using 200K test from dslreports/mspeed, Edge = 158kbit/sec.
Settings on GSM using same test 170Kbit/sec.
That's pretty close.
BTW, I'm using LVSW 5/19 with the 1.41 radio.

Did some more testing. The GSM/WCDMA setting does not affect the speed, its the Band settings that does. Try changing those and see if it makes any difference for you?
No need for "placebo" effects. If you have the fieldtest utility installed, you can use it to check the timeslot allocation - go to the GPRS/E-GPRS page, check the last parameter called "Slot Combination". It should say something like "5: 4R1T" (4 receive, 1 transmit) or "2: 1R1T" (1 receive, 1 transmit).
Hi, i was wondering how i would change the setting and if i would need any software to do it
Thanx in advance...
Its in phone menu, options, BAND tab.
I just tried it out of interest and ran a speed test and got 758kb/s over HSDPA with it on GSM900/1800 + UMTS2100 and 659 kb/s on Auto.
Using 1MB test on www.dslreports.com/mspeed
Auto = 148 kbit/sec
GSM(900 + 1800)+UMTS(2100) = 762 kbit/sec
Using Sleuths LVSW variant, radio 1.41
Both from exactly the same place on my desk at work
Well, I just tested. The result I got was slightly different. I got the 4R1T allocation with all auto settings. Interestingly, I did have a 1R1T allocation when I just checked from idle. When I loaded up some pages in the browser (to sort of "prime" the data connection) and then checked, I had the 4R1T allocation. All with the settings in auto mode. Just my experience.
i do not have more than 350Kb/sec... even though ot shows that i have a HSDPA connection... and the band set to manually....
Today I just changed my radio rom to 1.41.00.10 and tested the settings again. This time, there was a different behaviour. Neither the band or mode settings had an effect on the slot combination. In both cases, slot combination was always able to get to 4R1T. Again, this is on an EDGE network.
It seems the slot combination being limited to 1R1T on Auto band selection only affected certain radio ROMs - affected radios 1.38.30.10 and 1.40.30.10 for me (on EDGE). Seems to me like a "bug" on those radio versions. I might try 1.38.00.10 and 1.38.00.01 later.

Had similar experiences, although for me on radio rom 1.40.30, the slot allocation seemed to be stuck at 1R1T and didn't go to 4R1T unless I had the band manually selected. It could be different roms "ramp up" the slot allocation differently.
I imagine that the battery consumption with 1R1T could be a lot lower than 4R1T though. However, I found 4R1T connections to be more stable as well - sometimes on a 1R1T allocation, the internet connection would hang up a lot more - could just be bandwidth starvation.
Nice find!
Moved to hermes forum for more exposure.

yes, hardcore affiirmative on my side too with regard to 1.41 & changing of band settings from auto to UMTS 21000 ..not much different (slightly faster when not on auto mode) between both combo.. running the internet sharing when getting the results below (running 1.41 Radio with LVSW 3.30.2.1 ROM)
Test done with network set to Auto band set to UMTS GSM 900+1800 UMTS 2100
network=auto band=auto
network=wcdma band=UMTS GSM 900+1800 UMTS 2100
Update: I tested a few recent radio roms.
This seems to only have an affect on:
- Radio ROMS 1.38.30.00 and 1.40.30.00
- EDGE/GPRS connections (not sure about 3G/HSDPA)
On radio roms 1.38.00.01, 1.38.00.10, 1.41.00.10, the settings had no effect.
Is this the way it supouse to work?

When I start "browsing" IE the phone is able to get 4R1T, after few seconds (and while IE still displays "Opening") the Slot Combination data turns to "255".
BTW, I´m trying to determine why my data connection is so bad.... any help is appreciated.

The EV icon will stay the same, regardless of EV-DO revision, the only way you'll know if you're getting Rev. A service is if you get average more than 144kbps on the upload speeds, as Rev. 0 maxes out at that speed.
And yes, Rev. A service has been deployed in some locations and not others, if you're with Sprint, they have a coverage map online.
Hey, I've got a (rooted) G1 on T-Mo contract.
I want to check if I'm getting the fastest internet I possibly can. I know Haykuro's build display an 'H' instead of 3G if you're on HSDPA, but I'm using JesusFreke's latest cupcake build and it's my understanding that that doesn't.
So the question is, how can I check whether I'm getting real super wow omg 3.5G internet (which presumably I can, living right in central London) or just the regular 3G?
I've wouldn't normally think twice, but I've read lots online about having to enable it and there seems to be a lot of confusion. Also, it would be nice to know when I'm on 3G and when i'm on HSPDA, given that JF's build (kickass as it is) doesn't include an icon for it.

download xtremelabs speed test from the market. then check your max speed against max 3g and min hsdpa speeds that you have since googled to find out. while on haykuros rom, i got the h icon and i have full 3g coverage here in kansas city kansas.
Ilm in the same boat at the moment. When running Haykuro's H build I have H on Orange UK, the about status of the network says Ilm running on HSDPA but nettraffic says I have no connection speed unlike UMTS (won't work in other words).
I'm currently on JF's ADP1.5 rom based on htc build and only get UMTS. It would be nice to be able to have HSDPA but UMTS is fine...
Hey aad4231, thanks for your reply...
I'm a little confused, I thought UMTS utilised 3.0g services whereas HSDPA uses 3.5g? When using JF, T-Mobile or Haykuro's G build the phone uses UMTS according to system information and netmeter and nettraffic. When I use Haykuro's H Build GPRS comes up, then UMTS and finally HSDPA. Data services work while on GPRS / UMTS but as soon as HSDPA comes up there is no connection speed in system info.
I'd love to have HSDPA speeds (with Orange UK I believe it's 3.6mbps or smthg) rather than UMTS as I use my G1 as a mobile router with Wifi-Tether.
Thanks in advance again!
Run a speedtest (e.g. http://i.dslr.net/tinyspeedtest.html). If your downlink is greater than 384kbps, then you have HSDPA.
As been mentioned above, just because you do not have a H icon doesn't mean you are not connected via HSDPA. The H icon is present only in Haykuro HTC build because HTC added extra icons to indicate whether a 3G connection is HSXPA enabled or not. However, that does not mean that standard Dream software cannot connect via HSDPA. It does, but it will not indicate it. Again, confirm with speed test.
Just done a speed test using Xtremelabs speedtest from market. I noticed I'm now getting 843.5kbps since I flashed my G1 with JF's ADP1.5 last night. Prior to this I was only getting about 320kbps on JF's RC9/RC33 Builds.
Thanks for your quick reply and sorry for having to get you to explain again.

Thats pretty impressive, but as far as I know the different versions flash don't effect the speed. I believe that has all to do with the radio. Did you update your radio, that may have something to do with the increased speeds?

Actually the most likely scenario is just moment-to-moment variation in network usage. Packet-switched data services are usually delivered on a "best effort" basis. If you check the bandwidth at different times of day you will probably notice fluctuating numbers.

Yeah, Flashed the Radio with HTC's 1.5 from their Dream website. I do notice that speeds vary though throughout the day. In Mid-day I get about 400mbps but hadn't got 800mbps+ before, even in the evening.
Hot damn, it must be a low traffic day here in AZ. I just pulled down 1062kbits/s.
I just noticed that it says your network type on Settings>About>Status, so you can get an easy definitive answer rather than just running a speed test. Also has battery level which is nice. I made a homepage link to it on anycut for easy access
Downgraded to calkulins v1.7 since i was having issues with 1.8 and now i am not getting evdo connectivity at all. My phone only connects to 1x. Ive tried restoring my settings when i do ##3282# edit data profile and evdo. Im not sure what else to do. Ive flashed 3 different roms and nothing helped. What else can i do?
Sent from my PC36100 using XDA App
Go to settings, wireless & networks, mobile networks, mode of operation, and chose evdo only. This fixed my problem, hopefully it will help you.
I have no option to select mode of operation. I am unrooted now and back on bone stock ROM and still have this issue so I am not sure what is wrong. I am currently chatting with sprint to reset anything on their end. However, it still only connects to 1XRTT
try flashing 1.8 back and change the operation mode to hybrid. double check with ##3282# to also make sure the evdo setting is on automatic.

i just fixed this problem myself. go back to calkulin's evio 1.8, and change setting to hybrid. to see if it works, type ##3282# into dialer and choose view mode. go to evdo settings, and make sure its set on automatic. if not, then:
retrieve your msl (free app in market msl reader) and type the same code in, but choose edit mode. type in your msl, and go to evdo settings, and change to auto.
Ahhhh! I don't have this option :/

Changing to EVDO only helps with 1X, but I found out that the setting to EVDO only will not allow incoming text or calls. I had to put it back to Automatic.
I've tried everything everyone has posted so far. Changing to EVDO only and automatic and all that stuff. I took it into the Sprint store today and they tried telling me it was on 3G since the icon was showing that. I told them the evo icon never changes to 1x even when connected to 1x. She still didn't believe me. So I downloaded a few apps that showed my phone only connected to 1x and she downloaded the same app and it showed hers connected to EVDO. She said she couldn't trust the app and then she compared my phone internet load times to hers and mine was actually faster so she still wasn't convinced. I explained that the 3G is on a higher frequency than 1x and being indoors she may have a poor signal compared to mine. Also I told her that everyone in our area is probably connected to EVDO, thus slowing it down, versus just me on 1x, so I had better speeds. She said that is very true, so she ordered me a new Evo that should be here in a few days.

THIS WILL GET YOU 3G
but you will be constantly roaming
try it out and let me know if it works for you.
##775#
search for 00001.prl and change it.
commit changes and it will restart
give it about 10 mins to get connected right and do a speed test.
i was getting only 15-20 kbps using the latest sprint prl.
i changed to this modified prl and im getting 1700-2200 kbps
i think sprints prl's are messed up..
What test can o perform to prove that its versions network I am using after this hack? An iplookup says I'm still connected to sprint.

I'm having the exact same problems. Tried damn near everything at this point. No luck. If you find a solution, please post it.
is any radio version compatible with any rom, and what is the difference between at&t and international versions of the atrix. I got my mobile from the US and I am using vodafone Egypt...... does this make me an international or us
So far as I know, the radio version is independent of the rom. So you could have an international Atrix with the proper radio for your version as well as the proper kernel, and a US rom. Most roms do not touch the radio.
When people speak of different versions of the Atrix, they are referring to where the phone was purchased. The us version is slightly different than the rest of the world, and as such requires a different Kernel.
If your version is an AT&T version from the US, then you would use the us based kernel and radio.
so I am a US model...... Can I flash a radio that is not meant for at&t.... as your answer meant that I can but the last sentence in your reply says I cannot
I am shopping around for another radio as I have problems with 3G connectivity. I cannot have data connection whatever I do and I removed the apns and restored defaults and made new ones with the proper settings, turned 2g and 3g on and off and tried putting it in the flight mode and changing the settings for GSM only or GSM prl auto and all the other settings with no effect.
does the us version uses different frequency I checked my operator and found that they are using UMTS 2100 MHz
do you have any ideas............ I ran out of them

before flashing the radio did you make sure your apn is set up properlY?
yes I did and used 2 sim cards from 2 different operators working with the same apn settings flawlessly on other phones (blackberry torch and htc touch diamond 2)
I think, thought I may be incorrect, that you need to stick with the at&t radio if your on the at&t phone? Maybe someone who knows more than me can chime in?
I was just meaning that the radio is a separate thing from the ROM that you have on the phone.
The atrix supports 2100 mhz, so I suspect if you are having problems that it is connected to your APN settings.
When you are in the APN menu, did you try resetting to default before adding your APN? I usually have to do that on mine before I can get data to work properly.
