I just bought a BlackBerry Curve 8300 on At&t and I want to unlock it so I can use it on T-Mobile. I have no idea on how to do this. I have seen some threads on this forum but I dont understand any thing they are saying.
I would really appreciate it if somebody helped me out.
If you are a customer of AT&T in good standing they will unlock it for you. If not you will need to purchase an unlock code from a 3rd party unlocking service. GSMPhoneSource.com is a reputable one.
