Help!!!

[375sphelps]

ok, here's the deal, My wife has a TP2 that has been having problems sending and recieving email from Yahoo, sending and recieving texts, intermittently freezes and every once in a while the camera just opens up and snaps a picture... seemingly at random. one last problem, the phone says it is having connection problems anywhere from 2-8 times throughout the day. I've flashed the Rom to mighty rom, installed hard SPL.... any thoughts on a diagnosis or ways to diagnose this? Any help is very much appreciated!!!
