I have only had this phone about 7 months. The other day i had no signal for ages and My friend who is on the same network had plenty. So i turned my C902 off and tries to turn it back on, It loads up And then seems to freeze on the Sony Ericsson start up screen. I have left it on that screen for over an hour and nothing changed, ive taken out the batter memory card etc and put them back in and it wont load up! Ive never dropped this phone or got it wet or anything!
