I bought bb 8900 unlocked for my wife, i liked it so much except for the size of it so I decided to buy my self BB Bold. I purchased a new unlocked unit online, when i received it today i found that it is branded to At&t, (my carrier is tmobile) I put on my sim and the phone worked fine. I would like to know 3 things???

1- what are the risks and what would i lose if i unbranded it? applications, features .....
2- my wife's 8900 has Windows messenger, google talk, and yahoo msg all pre loaded, how and from where i can get these app for my phone?
3- i can't find the GPS icon, is it even installed???

Please help me before i return this device

1 you won't lose much if anything
2 you can download from www.mobile.blackberry.com
3 bold isn't supported by TMO so they may not have the service book for the gps for bold

Also be careful unbranding you can ruin the device permanently when debranding
