title says it all

title says it all. and does anyone know how to unlock it

You need to have it jailbroken (hacked). Then it will work with tmobile.

No, sorry. I've tried it before three different times, and the 'jailbreaking' hacking does not work. So dont bother trying.

Well it isn't called jailbreaking. It is usually just called unlocking a phone. It allows you to use the phone with any SIM card.

Hi unless you unlock your Iphone from AT&t network you cant use your T-mobile sim in it .To solve this visit Classicunlocking.com here they help you unlock your iphone from AT&T network using Remote Unlocking Service .Here they don't jailbreak your iphone before unlocking it .I hope it will be helpful to you.........
