OK let me go directly to the problems I am facing.
I bought a BB curve 8900 recently. I used it for couple of hours and then started to have the problem of auto rebooting of device while doing anything!. Then I took the phone to a repair shop who wiped out everything everything from the phone, basically doing a system restore of the phone but that did not help. It kept on rebooting at its will. After that I took it again to the tech support and this time he downgraded the OS from v5.0 to v188.8.131.52 (Platform 184.108.40.206). Things were going on smoothly with no reboots until after 24 hours the phone started to freeze at its will. Even if the LED was on it would freeze and the LED would still remain on!. And then after this it rebooted again. I am in a real dilemma. I really can't figure out how to fix this. I would really appreciate if someone could get my problem fixed!
