I've had my Blackberry 8330 for just over a year now and have had a continuous problem with it powering itself off. And I mean some days it will do it as many as 10 or 11 times. It's ridiculously frustrating and I don't know what the cause it. I can be texting, emailing or in the middle of a call and it just shuts down. And we all know it can take forever to come back up. Has anyone else had a problem with their phone powering off by itself? If so, what have you been able to do, if anything, to resolve the issue. Right now throwing it across the room is looking pretty good.
