Your current baseband should work fine since it is unlocked.

You can't put an I9100 modem on an I777. They are incompatible. However, you can put any number of I777 modems on there. They are all available in a sticky thread in the development forum. As azeem40 said, the one you have on there now should work okay. If the person who is receiving the phone is tech savvy, then perhaps you could show them where to get the modems and how to change it, so that they can pick the one that works the best for them.

Thank you very much, i thought that i9100 might not be compatible but since it is unlocked i felt it should work fine but was not quite sure and since i am giving it to one who does not know a bit about this stuff i thought if i could get some answers here i could make those changes back there to solve any issues, thank you once again.

You can refer the thread http://forum.xda-developers.com/showthread.php?t=1361393 for i777 compatible modems.

[Q] Is AT&T modem UCKH7 compatible with i9100?

Got the unlocked international SGSII and am currently using DLEV Rom 2.0 which is android 2.3.5 with XXKI3. I'm wondering if it's ok to flash the UCKH7 modem from the AT&T SGSII. I'm guessing that if it is compatible, it should work better than the modems that are not specifically made for the AT&T network? And yes, I did forget to mention I am currently in the U.S. Whaddya think? I'm getting anxious to try it but I don't want to accidentally brick my phone. Holla back!
Bumping this up. edifish, did you go for it? how did it end?
Was this ever tried? I also have an Samsung i9100 (international version) and am on AT&T in Texas. I would like to see if this modem would provide faster service in my area.
According to someone who tried data worked but voice calls didn't.
You shouldn't be able to brick the baseband, worst case reflash via odin. But still beware.

I was also wondering about this. Anyone else able to provide any info/experiences? I may try it myself but was wondering if a) there was any benefit and b) if there were any downsides (ie the claim above of voice not working). A second first-hand experience would be nice

[Q] Baseband/Radio for Australia (Sydney) Vodaphone ?

I am now with Vodaphone in SYD
Using Rarity Rom, with I9100TDUKF4...
the reception seemed to be very bad... any suggestion?
Also maybe becoz of CSC as well?
push.... a little help?
help......
Heya, I don't know much at all about modems, but seeing as no one else has any ideas I thought I'd just suggest for you to take a look at this thread:
http://forum.xda-developers.com/showthread.php?t=1277593
The second post shows a comparison between all of the modems that he tested.
I flashed KI4 just because.
I haven't noticed any differences (yet. I haven't really tested it out much) but then again I didn't have issues to start with.
Maybe worth a try? 8)
I've also found this and decided to flash it, too.
(Something to do with GPS stuff)
http://forum.xda-developers.com/showthread.php?t=1233256
Hope it helps!
I have been told local radio/baseband/modem will be better in terms of reception... not sure if that is true...
i'll give it a go anyway =]
In settings/about phone is your baseband 'dukf4'?

I'm using the I9100TDUKF4 modem with I9100 KJ3 firmware. Works well.
Give the Telstra I9100TDVKF2 modem a go. I found it better than the Vodafone modem for the I9100T.
Search for it in the Q&A forum.

Thanks all... I'm switching a lot of baseband today, KH3, KH4 is not good for T version S2s....
and yes, it was I9100TDUKF4 in basband before, that gave me an average speed and reception...
I have also aware that maybe the service provider will affect the reception, so my guess will be if for T version S2s, it has to be used different baseband when the phone is with Telstra and voda...
anyway i am using NEKF2 atm, the speed is amazing but the reception is again not much improved....

oh btw, i am living in Marsfied.... would that make a difference?
Yep! For i9100t it's best to use only the voda or telstra modems. I use kf4 on my telstra version running optus sim.
Does anyone have a cwm version of the telstra modem?

non-T version has tones of choices

Is it dumb to sale the ATT and get International?

The development activity on this forum is great. However, I've been checking out the i9100 forum and just 'wow' at all the activity occurring with the international version.
Would it be crazy to sale the AT&T one and pick up the International version? It's probably a noob question, but I don't really understanding if the ROM changes for AT&T are strictly tied to this forum or if some from the i9100 forum can be used.

I believe people get the AT&T version because they cannot cough up a ton of money for the international device. If you have that much money laying around and you ike the look of it, go ahead and buy it. However we do have design gears and a few others working with our AT&T device as well. It's a shame Samsung just doesn't make that phone available for all carriers. Then everybody can have an awesome phone.

You can't flash a ROM for the i9100 directly into the at&t version; you will run into problems such as the soft keys no longer working. Some devs are using i9100 rom files in their roms, though, such as Cognition 777.
You also might have to jump through some hoopla to get hspa+ working properly. People who got the international version before the at&t version came out had to do some tricks, such as giving at&t the imei number of a current 4g phone, so their phones would be identified as capable of 4g speeds.
Hellraiser makes it possible to flash any i9100 ROM on the i777 without issue. That package is flashed after the i9100 ROM and fixes the soft keys and other issues.

Makes it hard to fully explain to someone why android and not apple.
I didn't convince a friend to jump to android from iPhone, the phone did. I was getting ready to show him a feature and ended up running out of time on his lunchbreak. He said later just the little he had seen navigating the phone was more than he'd been able to do on his iPhone.

Not true at all. I'm currently running Criskelo v30 on my i777 and it works flawlessly. You can flash just about any GT9100 ROM on the AT&T version. All you need to do is run HellRaiser and HapticFix and you're good to go.

You can flash a GT9100 ROM on your AT&T SGS2 without problem. All you need to do is download HellRaiser Mod and HapticFix, place it on your SDcard and flash them AFTER you flash a GT9100 ROM. DO NOT REBOOT PHONE UNTIL YOU HAVE FLASHED HELLRAISER AND HAPTICFIX!!
Enjoy!

I'd stick with the AT&T version.
I'd keep the ATT version too. It is almost exactly the same as the international version, with the specific exceptions of the key layout, NFC chip in the ATT model, and a slightly lamer charging circuit in the ATT model, as well as missing FM. Its really just a tradeoff of "do you want FM or NFC?". Development is going strong for the ATT SGS2, and honestly, we have a larger choice of ROMs than the international owners, because we can flash Attain ROMs or i9100 ROMs (with Hellraiser).
Thanks for the information.
Can you point me to the HELLRAISE and HAPTICFIX mods?
Thanks.

What should I do to get it on the AT&T network?
I have already purchased the phone and the sim card from AT&T is already on its way here.
I have tried searching but I only find threads on rooting and flash custom roms but I havent found one that states which rom would work for International phone on ATT's network
Any help would be appreciated. Cause I am now worried I bought a $700 paper weight I cant use.

The international one WILL work on at&t, I think the op was kind of misleading.
It seems slim thought you were asking if international roms will work on US S3.
Tbh I thought the same.
Any rom in the development section here will work on your phone. No problem.
Just as long as its the international model, GT-I9300.

My bad. Yeah, it's one of those confusing sentences. If you have I9300 then whatever is in this board will work.

AFAIK the I757 aka 'Sky rocket' has an entirely diff hardware config compared to I9100 hence, installing a software meant for the I9100(international) on ur phone might lead to a hardbrick, u have a dedicated section for the same.please visit there and check

This phone is made by bell. So I can only flash the ROMs that are only made for this phone? I cannot flash skyrocket ROMs? There are only like 2 ROMs for this phone :9
I've bought an i757 too and im a little decieve at the fact that there is only two Rom available for this built.
Well. I love it anyway. I find it more interresting than the original gs2 an much more cool than the ugly gs3.
And the CM10 Rom is getting better each day. So there still hope.
