ive found this broken screen BB 9780 with mexicos carrier Movistar on it... replaced the screen, put my brazilian Vivo's sim card in and i am sucessful on using everything a standard data plan allows: everything but bbm and email while on wifi, and everything but app world, bmm, email and bbbrowser while on radio. (problems with bb maps too)

the problem is that all of sudden, every now and then, i stop receiving data (either radio or wifi) at all until i reboot the system. if i dont, all the signal indicators continue to show bars and , but any internet app wont work... and reconnections wont fix the problem.

last time i happened to see the led indicator for "missing signal" right before the problem occured.. so im thinking its happening due radio signal break or constant edge/gprs/3g changing that is happening quite often with my ty carrier

does anyone have the same issue? any inphone change i can make that may fix it?
thanks in advance
