Bold 9900 Freezing problem

Hey guys,

I have a Rogers Bold 9900 and am having a problem where the phone just freezes and locks up. It has done this two ways, one with the backlight bright(i keep brightness at 10) and frozen, the other way the backlight is actually dim and frozen. It usually happens when the phone has been idle and i pick it up to use, pressing a button triggers the lock. The phone wont respond to the alt-shift-del when this happens, I have to pull the battery and do a hard reset. This happens about once every 12 hours approx.

I just started using the phone a couple days ago and its happened since. I bought the phone used but I did a fresh install of the most current rogers software which is 7.1.0.746. Should I try downgrading to .391? If anyone can help me out that would be great, thanks.

i updated to the at&t 7.1.0.862 i hope this resolves the problem.
