I have been having some problems with my htc dream on rogers ive had it since december and everything was going fine. but now i seem to have some problems which are sometimes i get a system error in which case everything freezez so i have to switch the phone off, but when i switch it back on it freezes at the rogers screen and doesnt come back on. so i have to factory reset it which i think i learnt on this forrum. but the problem with that is everything gets deleted. any idea of how to fix the problem?
