Yes, you can unlock your phone using www.myiphoneunlocker.com i have used their software and it works a treat, also it gives you lifetime upgrades, so when apple release an updated firmware on iTunes, you can update to it, then unlock your phone again at no extra cost.
When unlocking for t-mobile, make sure you turn OFF the 3g setting in the iphones settings menu otherwise your phone wont recognise your sim.
No it is not. It is for AT&T unless you "jailbreak" and "unlock" an iphone. Instructions to do this can be found on the internet.
No, unless you illegally unlock it.
No, T-mobile does not have the iPhone. AT&T has it though.
you can tbuy an iphone without at&t.....
T-Mobile does not have the Iphone only At&t does
There will not be an iPhone 4S for T-Mobile but you can get any iphone unlocked at unlockatt.com
The iphone4 is not coming out on t-mobile.
You either have to purchase an unlocked iPhone or jailbreak and unlock it yourself after you purchase it. This process does void any manufacturer warranty.
yes you can just go to unlock att .com and after you process it you will be able to use it on any service !!
Of course you can. T-mobile, AT&T, and Cingular are available. You can go to customer support and request it if you are off of contract (an possibly the original owner), or use an internet service like iFactoryUnlock which can to AT&T in the USA but not T-mobile iPhones.
you will have to jailbreak and unlock your iphone , there are lots of tutorials on this on websites. theres a tutorial on how to do this at : www.iphone-mod.com
Not yet in the US (nobody really knows when), but outside the US, some T-Mobile subsidiaries do, from what I've read. If you use your iPhone in the US, you can unlock your iPhone using one of several hacking tools, and then T-Mobile will be happy to sign you up, either for phone-only service, or phone and data. It's a little cheaper than ATT, and depending on where you use the iPhone, you might get better (or worse) reception than with ATT.
