No, unless you illegally unlock it.
no, you dont. you can jailbreak your iphone and run it on tmobile's network, if you have a tmobile sim card. but on tmobile, you cant have 3g speeds, only 2g.
Yes it will, but it will not support 3G. It works on the Edge network just fine.
Can you use a verizon iphone with tmobile account
I would believe so, it can be difficult to unlock your iphone though but the iphone is exclusively at tmobile in Europe.
February 2013.
You mean you want to use your tmobile phone on Verizon network? No you can't. Verizon is CDMA and tmobile is GSM network, so your phone won't work on Verizon netwok
no unless it is unlocked... .
It will come out in 2013its about time
Yes, but the iPhone 3GS will probably only work on the slow EDGE network because it lack's the proper antennas to use T-Mobile's strange bands of 3G and 4G.
To unlock your iPhone with you Tmobile SIM card I would suggest you goto easyiphoneunlocker.com they have a very easy to use tool to unlock and jailbreak your iphone. I was able to unlock my iPhone 4S within in 10 minutes with no issues.
Yes I have a iPhone On tmobile and no Internet
Tmobile has the largest 4G network available. Tmobile also has the fastest service network out of all of the other carriers. They also have a high speah 3G network just in case you don't want to take the extreme plunge into 4G.
