I don't think so.
Sprint is CDMA network while T-Mobile is a gsm network. I don't stay in the US, but I think this info should be correct
Swyped from my Galaxy SII

[Q] Can ANY Vibrant be Unlocked?

im planning to buy a Samsung Vibrant to use it with another carrier, my only doubt is if ANY Vibrant CAN be UNlocked?
Thanks in Advance.
Yes all vibrant should be able to be unlocked, just make sure that you have a sim card that is not t-mobile

unable to get into recovery or download mode using the physical keys.
Why you want to unlock a Vibrant to use on another carrier? All of the 4 major carriers in the USA has a Galaxy S model. Use the one that your carrier has.
By the way, if you unlock the Vibrant it will only work on GSM networks (AT&T and TMO)

I want the Vibrant because it definitely has more dev-support. Also I like it more i9000-ish.

Telcel uses the same 3G bands as AT&T (850Mhz/1900Mhz); T-Mobile on the other hand uses 1700/2100 MHz. When it comes to 2G, both T-Mobile and AT&T use the same frequencies.
So basically, there's nothing to fix. If you wanted to use Telcel's 3G network you should have gotten a Samsung Captivate and not a Vibrant. The phone will work, but you will be limited to 2G speeds.
You said it works with Movistar though, so perhaps your best bet would be switching carriers? Still, it's a really sweet phone even if you can't use Telcel's 3G network.
Suggestion
Actually, I think you should be after the Bell Vibrant instead of the T-Mobile's Vibrant. Either that or the Captivate.
Both the Bell (Canada) Vibrant and AT&T's Captivate have the same 3g bands as Telcel and Movistar (850/1900 3g). I would go with either of those for full 3g coverage just in case the 3g down there is as weird as AT&T's (From what I've read AT&T is kinda transitioning it's 3g from the 1900 band and pushing it more onto 850). Besides, not too many places support T-Mobile's Vibrant 3g band (AWS).
Can non-activated Vibrant be unlocked?
I've read related threads but haven't found an answer that really helps me. I'm buying a new Vibrant from someone tomorrow that hasn't been activated yet. As soon as I get it I'm planning on unlocking it to work on AT&T. Will I be able to unlock the Vibrant if it hasn't been activated on T-Mobile yet? Thanks for your help.

Yes you can, the first thing I did after finishing with the unboxing of my Vibrant was unlock the phone and instert my At&t sim card... no need at all to first activate with TMO

Awesome! Thanks a lot. Did you use the Samsung Galaxy S Unlock Tool to unlock yours?
If telcel uses the same bands as at&t then you should have 3g try seeing which band your phone has checked to on. 850 is disabled by default if you go to one of Eugene's froyo builds thread there you will see how to enable the band to have 3g on your phone for that specific carrier which is most likely the 850 band.
Try that if it doesn't work sorry I tried to help. I hope it works for you though enjoy your vibrant.

Did you have to root your Vibrant before you could unlock it? I tried to run the unlock tool but it said no codes could be found. I had read that some of the newer Vibrants were firmware locked so you have to root before you can unlock. This one is brand new so I'm guessing I need to root it first. Any thoughts?
Maybe, idk. I've had my vibrant since it came out and its been rooted so I can't help you there. Why don't you just root?

MetroPCS? Will this phone (specifically the GT-I9100) even work on their network? I thought they were a CDMA carrier?
EDIT: hold up. You say "about to get Galaxy S2 I9100 switched over to metro"... does this mean you already have the phone and are switching to Metro? Or did you order the phone and are waiting for it to arrive, and plan to switch to Metro?
Your profile says you are on T-Mobile USA. If you ALREADY have a Galaxy SII on T-Mobile, you probably have the SGH-T989.
If you DON'T already have a Galaxy SII, and you've ordered the GT-I9100, and want full use of 3g/"4g", you will HAVE to go to AT&T or H2O, or any other GSM carrier that may be regional to your area that uses the same frequencies as AT&T. Or, you could stick with T-Mobile, but your mobile data speeds will be limited to Edge.
MetroPCS uses completely different cellular transmission technology, and the GT-I9100 will not even pick up a signal on their network for voice, let alone data.
EDIT 2: For that matter, if you have the T-Mobile variant (SGH-T989), that one won't work on Metro either, for the same reason.
Well it's both I'm picking up the phone after work and I plan to get it flashed to Metro. I was told that the phone is the Sprint Samsung Galaxy S2 I9100. I'm doing it for my girl who already has Metro. I have seen other user selling Galaxy S2 already on Metro so I know for a fact that they have the Web & MMS working, I just cant find it for myself! Thanks for the reply by the way!

Who ever told you "Sprint Samsung Galaxy S2 I9100" is wrong. There is no such thing.
The I9100 is the international model that operates on GSM.
If it's from Sprint, they meant the "SPH-D710", not "I9100".
You are better off asking in this forum. Someone there may have experience flashing a Sprint variant to Metro.
It's not very likely that anyone here in the I9100 forums is going to be able to help you, sorry.
I think he posted the wrong model>>>>> What Carrier has Galaxy S2 model I9100???? I think sprint model is Sphd710!
Thanks for the Help!!!!

If he said it's flashable to Metro, then yes, he got the model wrong.
NO carrier in the US carries the I9100. It is the international model. But like I said, it works on AT&T for voice and 3g/"4g" (which is what I'm using), and T-mobile USA for voice and Edge.

[Q] What's carrier can the Galaxy S II be flashed to?

Hi a friend of mine wants to trade his Galaxy S II for my Evo Shift. I'm pretty sure it's worth the trade but before I do I wanna know what's possible on it first.
What all carrier(s) can the Galaxy be flashed to?
What's the best performing/fastest carrier available?
And is the flashing process easy?
Thanks in advance

What country? And what model of Galaxy S II does he have? What carrier did he get it from, if any?
There are over a dozen different models of Galaxy S II, and they are all different. Some are GSM, some are CDMA. Some have LTE, some don't. So what carrier the phone will function on will depend on what model it is.
EDIT: You say you have an Evo 4G Shift, which makes me think you are on Sprint, in the US. Is he also on Sprint? If he is, then the Galaxy S II he has is not the same as the one this forum is for.
THIS forum is for the GT-I9100, which is a GSM phone... which means it works on AT&T and T-Mobile (but only with Edge on T-Mobile) in the US.
The one from Sprint (a CDMA network) is the SPH-D710, also known as the Galaxy S II Epic 4g Touch. (Its forum is at http://forum.xda-developers.com/forumdisplay.php?f=1281) If this is true, then I've heard you can flash the Epic 4g Touch to other CDMA carriers (like Cricket, Verizon, US Cellular, etc)... but I don't know the details. If he indeed has the Epic 4g Touch, then you would be better off asking in the forum for that device.
Ok I was not aware of that. But yes it is a sprint version which would make it CDMA. I didnt realize there was a difference between carriers. But thank you anyway for the help!

Probably. And this isn't the right forum for the ATT Galaxy S2. That's here.
Most AT&T phones will only work on edge for Tmobile. i777(AT&T SGS2) will only work on edge.
