Just a few questions:
For those using an unlocked Galaxy S in the US, is there any 3G (data) issue you are noticing?
How is performance and availability of 3G with 1900Mhz spectrum when using a Galaxy S?
I am in NJ (Mercer county) and was wondering if anyone here was in NJ and had an unlocked SGS on AT&T and whether they were getting mainly EDGE.
How will I get official patches or Android updates for my unlocked SGS, does anyone have a link to a download page?
Where did you buy? How much?
H77P://negrielectronics.com/samsung-i9000-galaxy-s-black-8gb-unlocked.html
Updates should go through the samsung kies software (available on samsungmobile.com) or OTA. OTA is definitly possible even with unlocked handsets as I have received them on my unlocked htc desire.
Don't know which method samsung will choose tho, since I haven't received any updates so far.
Any user of an unlocked SGS in USA that can comment on the AT&T 3G (data) performance in the North East region?
I know AT&T is moving most 3g to 850Mhz but I cannot imagine that they would abandon 3G on the 1900Mhz spectrum since international (GSM) travelers would be unable to get any 3g when visiting (especially for business travelers).

They are not moving anything off 1900Mhz, they are just adding new 3g towers only on 850Mhz.
If you had 1900Mhz 3g in your area, it is not going to go away.
If you did not have 3G in your area or had spotty 3g and recently got good 3g then it is probably on 850Mhz.
I have same issue in my use. Used 2 get 3g off of i93. Thiswith my i8910 euro phone on 1900 now only edge same on galaxy. So they r definitely moving towers to 850.

nice nice nice!!!
Thanks for all the information guys.
From what I am hearing it seems that this is a well designed phone (except for the plastic feel of the back and the lack of a flash for the camera).
This is my fist android phone and as a person who is seriously tied to my corporate email system (Exchange 2007), I can only hope for a quick implementation of Firmware 2.2 which will allow tighter integration with office systems (SSL VPN and Exchange).
I am really hoping to get this phone soon and I will be flashing it with the latest firmware as soon as I open it.
On a side note (not that I would try it without someone else going first) is anyone testing MoDaCo's custom build with WJG1 as the base? Also, if I am running a custom ROM I assume that when an official build is out I have to wipe and re-flash with an official build first before upgrading to 2.2?
I GOT IT !!
So far I am really loving the phone. Since I like breaking things I am going to flash it now with the latest FW since it has this singtel firmware.
Now I just have to find a way to rip all the DRM from my apple/itunes songs to be totally free.
Quick question, the email client sucks. I need to only let it pull email from my "inbox" folder not other (Exchange) email folders, How do I configure it to do that? Or is there a better app for corporate email that I can use?
<farnsworth> Good news everybody! </farnsworth> I have the european i9000 (900/1900/2100) which I bought unlocked in New York City and have been using (with 3g/HSPA) on AT&T.
When I came home to canada, I got a bell sim card (as I have a bell plan, previously with a CDMA phone). When I started the phone, all I was getting was voice, and I was very dissapointed.
I decided to see if Rogers or Tellus would work (as somebody told me they use 1900 more than 850), and when the rogers guy tried his sim, it was the same story. THEN he figured out that for this phone, you have to manually enter the APN info for the canadian carrier. He tried it on my phone, and I started picking up EDGE.
I immediately called bell tech support for the same info, and they referred me to the website. I entered the bell APN info in the settings menu and I now have HSPA on bell in Canada on my european i9000! Spread the word!

Yeah but on the countryside 850 is the main frequency as far as i know..
Even in cities it isn't everywhere
I think i read it on engadget some time ago
Sent from my A101IT using Tapatalk
It works for me in every city around the golden horse-shoe (Toronto, Hamilton, St. Catharines, etc), even in rather rural places like Niagara-on-the-Lake and Fort Erie. I haven't tried it in Waterloo (where I go to school yet), but that is a big technology town so I'm sure it will work. Coverage in these areas is enough for me I'm just trying to shut down the "this phone will not work with bell canada's 3g network, it's been tested by multiple people" I've heard going around.
Well my euro did not get 3g around Niagara falls and here in th usa did not get 3g on most of the Boston nh i93 corridor which uses 850 mhz

There are two specific Kiwi issues I would like to discuss.
Does anybody know where to obtain a stock ROM for the I9000 from Telecom New Zealand? I believe there is only Eclair, but would like to be proven wrong. I may require this in case of any warrany issues and to reset before upgrading to Gingerbread (at least I am led to believe this).
Which modem are you using (again Telecom NZ) on your custom ROMs? I have tried a few and I am currently using JL2. I had to flash this separately while using Darky's ROM 9.3, which worked fine in some parts of town but not at all in others (I presume it could not handle the 850 band).
Many thanks in advance

I believe JL2 is the correct modem to use. Do you have a Telecom SGS as the Vodafone one obviously does not support the 850mhz band that Telecom requires. It is possible that the rom/modem combo you are using disables the 850mhz band which would explain why some parts of town aren't working. I'm pretty sure there is a way to enable it if your hardware supports.
As for the thing about the stock rom, I think maybe you should ask people on the Geekzone forums - http://www.geekzone.co.nz/forums.asp?forumid=97&topicid=62267&page_no=323
telecom froyo
I have the telecom froyo release even though it has not been released officially.
i got it from Modaco,(i think cant quite remember), if someone could tell me how to post a download link i can put it up here. Also i have a rom which makes it relly easy to get 850Mhz back. Im at work at the moment so cant post that yet either.
Im using JVE modem with multi csc which works great in new zealand, JVE good for battery too.
pm me if your interested.
Choice one.
Keeping all the New Zealand info in one thread for neatness.
I've just moved in New Zealand from UK. I have UK SGS I9000.
Which New Zealand network would you recommend getting a Sim Card for?
Should I switch my ROM to a New Zealand based one? Hoping to use the free SatNav software too (is it called Navigon or something?), in case this makes a difference on ROM choice.
I've been told that 2degrees is the cheapest network.
Are there any hardware / software limitations on which network I should choose with a UK unit? 850Mhz band availability?
Love to hear your thoughts...
Thanks
Mike
Welcome to NZ. The network will depend on your location: 2 Degrees is cheap but has low coverage in rural areas, Vodaphone is ok in cities. I am with NZ Telecom, they get a bit of flak for problems they have had in the past. However, they are investing huge amounts and have the best rural coverage. Please be aware that your phone will have to use the 850 band in some areas.
I recommend the JL2 modem (ROM kitchen) and Darky 9.3 with Voodoo kernel.
Navigation for GPS use.
I'm with 2Degrees and they're cheap. But as a poster above had mentioned, the coverage outside big cities is limited, especially for data. This of course will change with time. Plus I'm a big supporter of NZ owned businesses.
Vodafone is a horrible company to deal with. Plus they have a lot of network issues everywhere in the country.
I have heard good things about the XT network (Telecom) in terms of speeds and coverage. If I wasn't on the tight budget, this is what I would choose in NZ. I hope this helps. :>

Just a quick correction, coverage is fine as the device roams on Voda when out of zone. So if there's voda coverage, there's 2degrees coverage (data is not as cheap though).
I'm using CM7, JPM. All seems fine.
Hello from Hamilton.
Thanks for the advice.
I'm probably going to be mainly in the Wellington region, so should have reasonable coverage on any network. Glad to hear that 2degrees has roaming on Voda though.
Will my UK I9000 SGS have 850MHz band available in the hardware? (sorry if this is a silly question). Will it be used if I have the correct firmware? Is 850MHz band used by all networks in NZ, or only for some networks?
All of the networks appear to be quite pricey for data. Who are the most cost effective for data? I'll be looking for either PAYG or Monthly Sim Only deals.
Thanks again for the great info.

I presume you're talking about 850MHz 3G and not 2G.
Vodafone and 2degrees have 900MHz 3G.
Telecom has 850MHz 3G.
I think your UK i9000 supports 900MHz from what I have managed to find out.

ive got an international i9000 that i bought before work (telecom) stocked them - so I cant get staff subsidy on my cell heh - I have 2degrees - because of the data pack and living in town - it was bad coverage where i lived out on the west coast at murawai - but in town i have no issues - even in the middle of the telecom borg cube building - i get my 2degrees data and voice coverage
I cannot recommend anyone to you - but I have converted some of the telecom staff i9000's to darkyrom's The theory is that version of the rom supports the 850mhz band - I guess I find out tomorrow with one of them
About backing up your factory rom - root the rom is the minimum first step and then you can make an odin image out of whatever is on the phone.

I've gone with 2 degrees for now on a simple pre-pay sim and all looks good. I'll see how much I use it and maybe get an appropriate monthly contract if needed in the future.

Quick further question...
Which CSC code do New Zealanders have? Should I, stick with my generic UK code, or move to a NZ one? What do you use and recommend?
Does which CSC I have affect my ability to use Navigon for free?
(I forget what my current CSC code is, but I noticed my Google Market is now priced in NZ dollars already, but they want to charge me for navigon download, which I thought was free over here. Ultimately I'll deal with Navigon, in the Navigon thread, and ask about CSC here... Just wondering if there is any implications of what makes a better CSC.)

If you've rooted your sgs then try using this app called GPS AIDS from the market. Its very good, i usually get a gps lock in 5-10 seconds indoors with a cold start.

Yea, I've been using that app for a while now.
It is very good indeed.
But I would like to improve it more by chaning gps pool through this app actually.
I was wondering whether I should use NZ server for gps or worldwide one...
Set to oceania.pool.ntp.org using FasterFix or other suitable apps.
Has anybody gone 2.3.3 yet? If yes, what about the modem performance on the XT network?

Sorry, I cannot answer that with certainty. I do not believe that there are vast differences. I have tried Asia, North America and our version Oceania. I am however, very unhappy with the GPS performance, in particular the length of time to get a fix. Needleess to say, I have followed most guides and tried various fixes. I am, however, limited in changing modems as I rely on 850mhz band.
I missed up my Telus 4G 10.1
I could restored back but it seems I used unbranded 3G stock rom
it works fine but network mode showing CDMA not HASP+ as expected from 4G
so it behave as 3G not 4G
if anyone can post canadian stock rom or even a backup that would help me to bring back to normal
don't have the original firmware for my Rogers Tab. They are labelled 4G in Canada but that is actually 3g+ (there is a nice wikipedia discussion you can look up) and the Rogers model at least, will only run on 3G firmware not the LTE versions you can access -- the bootloader on mine has KG8 as its firmware, you can download that from sammobile if you want to restore your system or you can download the latest 3.1 firmware Ki2 here on xda or through check fus. The most recent firmware is 3,2 and there is a stock KJ6 version and a custom version Overcome 2.0.0 available.
The 3.2 based roms are significantly smoother,faster and without the launcher and browser lag sometimes evident with 3.1.
So, if its just to maximize your own use, I would suggest either stock or custom 3.2 firmware -- again, they will all show 3G as designation.
I already installed the KJ6 3.2 which runs very smooth with no problem
but I can see only CDMA or GSM
what you see in your network mode is it CDMA or HSAP as mentioned in user manual
and if I have a data plan up to 21 mb/sec do I can get this speed with this KJ6 rom
download network signal app from the market: it displays the signal our device is actually receiving on either wifi or 3G+: the device will support the speed, it whether or not you are in an area with that coverage
rogers will show umts
as wikipedia explains
UMTS supports maximum theoretical data transfer rates of 45 Mbit/s when HSPA+ is implemented in the network.[2] Users in deployed networks can expect a transfer rate of up to 384 kbit/s for R99 handsets, and 7.2 Mbit/s for HSDPA handsets in the downlink connection. These speeds are significantly faster than the 9.6 kbit/s of a single GSM error-corrected circuit switched data channel, multiple 9.6 kbit/s channels in HSCSD and 14.4 kbit/s for CDMAOne channels.
Since 2006, UMTS networks in many countries have been or are in the process of being upgraded with High Speed Downlink Packet Access (HSDPA), sometimes known as 3.5G. Currently, HSDPA enables downlink transfer speeds of up to 21 Mbit/s. Work is also progressing on improving the uplink transfer speed with the High-Speed Uplink Packet Access (HSUPA). Longer term, the 3GPP Long Term Evolution project plans to move UMTS to 4G speeds of 100 Mbit/s down and 50 Mbit/s up, using a next generation air interface technology based upon Orthogonal frequency-division multiplexing.
the last iteration is LTE which we can access using the 7500 version we have but not with the sim card we have
Howdy! I have a stock Canadian (Telus) Samsung 10.1 4G [GT-7500DTLSKH4]. If you'd care to provide explict instructions (for this Telus model) on how to root and backup rom, I can archive and forward. If you also have instructions to "unroot" said device, that would be greatly appreciated, too. Further, have you received the 3.2 update for this model as of yet? If you have, was it VIA WIFI or OTA? The reason I ask is that it informs me there are no updates available (I use WIFI only at this time).
Thanks in advance!
Thomas
For Telus:
www.sammobile.com/firmware/?page=3&t=3&o=1&m=GT-P7500D&r=-1#modelsa
Rogers, and Bell also at SamMobile Firmware page.
Telus is 3.1 (as is bell)
Rogers updated to 3.2 but has lots of rogers crap. ALSO note your telus sim with this firmware will pull the wrong apn, it'll get sp.telus.com and leave you with a HUGE data bill. SO if you use it make sure to change the APN before connecting to mobile data to isp.telus.com

I hope you will forgive me for clarifying but I have the 7500R and I could flash the 7500M bell firmware to it with no issues?
Before any one asks why I would like to ask my other question... Has any one seen a Galaxy Tab re network lock? My device was unlocked since like November and all of a sudden today I am getting the SIM network unlock PIN. I tried the original unlock code but it doesn't work. As well I took the bell sim and used it in the Nexus S and accessed data so the sim seems fine. I know this might need to go to another thread but I thought maybe I should try flashing the bell rom? As well maybe I should just try a hard reset first? Any suggestions.
Thank you...
So it turns out some how it must have relocked... I used an app from the Marketplace that I linked to from XDA and unlocked it again... The original unlock was a code entry so I'm not sure why or if it should have relocked but I am back up and running now.
Sorry for the super late reply, I don't really monitor the threads.
Anyhow yes you can put any of the Canadian firmwares on your Rogers Tab. Or vs. No issues I've seen to date.
As for your second issue. A few months ago the same thing happened to one of my tablets it seemed to relock itself and would no longer accept the factory unlock code. I had to edit the nv file directly to fix that issue. And strangely enough another phone I had from Telus Samsung facinate 4G, did the exact same thing, and then another when that one was replaced by Samsung. On the facinate using a telus sim the phone would still ask for a unlock code. So something strange was happening. The phones were brand new, and never rooted, completely stock. The only thing I did was put in my kodoo sim and enter the unlock code.
So three devices in total did it.
No problems on the late reply. I ended up using an app by one of the xda members to edit the nv as you mentioned you had to do. I am actually very glad I purchased the app as it appears if you dont reverse it to check for firmware upgrades it is failing to connect.
In regards to the roms does anyone have any experience with one being better then the other? I am using a bell sim so was just curious if I should flash bell firmware.
Thank you for your reply.

Hello all, I just bought a Defy mb525 green lens off amazon. I'm in the United States and my sim card is from T-mobile. The phone is from south american (not sure which country)
With the stock rom everything worked fine.. but after i installed cm10 all i got was emergency calls only. I tried all the T-mobil basebands.. as well as every other baseband.. not once did i ever get a signal of any kind.. at one point my phone detected at&t but still had no signal..
I then tried cm7 but had the same result..
I then tried stock cee just to settle on something that works but got rid of blur.. but still had no signal..
If you live in the United States and are on t-mobile wat baseband do you use? Could the issue be with different hardware due to the phone being made for south America? (although with the stock rom i have a great signal) Any comments or suggestions would be much appreciated..
Thanks in advance,

I have a similar issue with a Defy MB525 that I bought as a refurb from Amazon just a couple of weeks ago.
When I received it, it seemed to be set up with Spanish as it's primary language...
Anyhow I reflashed it with a motorola sbf file that allegedly was for Tmobile USA and had Android 2.2.
Then I rooted it and loaded up CyangenMod 7.2...
I have a SIM from Lycamobile USA, which rides on the Tmobile network.
Before fiddling with the various baseband selections available via CM7.2 I could not make any calls
Phone info, baseband version:EPU93_U_00.59.01
Partial solution.
Tried all of the TMobile/USA baseband settings - no joy.
In desparation tried some of the SouthAmerican settings and the Asian settings...
The best of the lot seems to be Asia/China/ME722 1.10 850/1900/2100
Which works okay and gets an "all bars" signal for me - for Voice and Edge data.
I suspect this setting works because T-Mobile operates Voice and Edge on 1900Mhz in my area.
Also, in some areas, I get "emergency call only", which is probably on the 850 band that belongs to AT&T.
Problem
I don't get any 3G service. That's probably because, as I understand it, 3G for t-mobile is using 1700/2100 (up/down or vice-versa)
and my radio isn't set up to use the 1700 Mhz band.
Question
Can I fix this with a reflash of firmware - to exploit "quad" band operation 850/1700/1900/2100? Which are all in use by Tmobile and/or AT&T in the USA, according to various Wikipedia articles.
If so, which firmware should I load?
If not, is this a hardware limitation of the Defy MB525? Some builds/versions? Or all versions/builds?

And no, in most countries you won't get 3g, since this is a hardware issue. I get 3G in Ecuador, but that is only because Movistar here uses 850mhz band for UMTS. Another option would be to sell your Defy and find a Argentina Personal Defy which uses 800/1900, or buy a European Defy that uses 900/2100, since I think in almost every South American country there is at least one carrier that uses those frequencies.
But T-Mobile's defy in South America, as far as I know, will only get you 3G in Ecuador.
EDIT: Misunderstood the post, wasn't paying attention , but my point is still valid. It's a hardware issue.
Update - MB525 Tmobile Melrose MA seeing HSPA

I use the Colombian frequencies, better battery life than Chinese. But yeah, occasionally on some stock builds I wouldn't get any signal.

I'm visiting Melrose MA today and I'm seeing an HSPA signal! Still with the "China" settings...
Speedtest.net says I got:
Code:
Date,ConnType,Lat,Lon,Download,Upload,Latency,ServerName,InternalIp,ExternalIp
"2013-06-21 15:32","Hspa","42.45245","-71.06685",1388,988,282,"Boston, MA","10.230.130.121","83.137.2.146"
"2013-06-20 07:49","Edge","41.33962","-73.37708",198,112,467,"Secaucus, NJ","10.230.142.199","83.137.2.147"
While the "Network Signal Info" app says I'm HSPA at 14.4 Mbps, I guess that's a max.
Soo... this is good, but I'm still curious -- how can I determine which band(s) the radio is operating on?
According to Wikipedia, T-mobile runs HSPA on the 1900Mhz band in some areas and 1700/2100 in others...
Since I set my radio to 850/1900/2100 - my first guess is I've wandered into a 1900/1900 HSPA zone...
My connection is to CID13693382 / LAC 36498 MCC-MNC 310-260 Is there a database where I can find out what frequencies are assigned to this cell tower for T-mobile? Lots of location/map services - but I didn't find any info about baseband allocations in this area...
Hmmm... Let's try switching the baseband to the T-mobile USA 6.x settings...
Same result as in CT, no service, no joy ;-(
Do the T-Mobile USA settings work for anyone watching this board?
