I recieved an unlocked 7105t from a friend that has been unlocked. I currently have service with Cingular, and I can not get the internet nor MMS to work on my phone. Is there anything I can do to get this internet service, or MMS up and running? Cingular does not want to help seeing as how this was originally a T-Mobile phone. Any help is appreciated. Thanks.

Are you signed up for a BB data plan? You MUST have a data plan in order for internet to work.

I also have an unlocked 7105t with Cingular and I have the same data problem, which I can live with for now. The main problem I have is that when there is an incoming call, the screen notification comes up but the sound doesn't work (yes I have the sound turned on and it works).
