T-Mobile Generally has the V3r, which is impossible to unlock (Unless you have a smart clip). Do me a favor, and turn on your phone whilst holding the asterix (*) and the pound (#). If it says: SW Version: R4515_G_08.BD.2AR_2 You're out of luck, I paid $25 to unlock mine at a place called 'Blue Ridge Wirless'. http://www.blueridgewireless.com/ You can in theory send it in to them, but there is no point, as all they use is a smart clip, so many outlets/phone repair places should have one. Also, Do not post your IMEI# it's personal information and can Identify your phone/your name and a whole load of other things. And, please do not post a topic with the title "helppppppppppppp", Mainly because it pisses people off, and you WILL NOT get helped before anyone else with a title like that.
