HELP needed to unlock AT&T vendor id on 8820
Please Login to Remove!
Someone please help me. I have an unlocked 8820 which I got when I was with AT&T. Now my carrier is T-mobile. I heard that I can make UMA calls if I remove AT&T's vendor ID and replace it with T-mobile's vendor ID with the hope of activating the UMA feature once the AT&T vendor ID is replaced by T-mobile's. I've read different posts and picked up bits and pieces of information. There was one post that said that there are specific instructions on how to do this in the FAQ, but I've searched and couldn't find it. From what I've read, I understand that I'll need some file called blackberry.axl for 8820. Anyone with the insight on how to do this PLEASE help me.
Thank you for all your help.
