I have 2 unlocked blackberry phones originally manufactured for T-Mobile. One is a Pearl 8100, and the other is a 9780. Once I got a mobile share plan for my AT&T service, the 9780 is able to use data..but the 8100 can only load stuff in the browser...but none of the other apps are able to use data, like bolt browser, or google talk. Does anyone know how I can get these working?
