I've had mine since 4/30. It had no issues for the first 2 weeks. Then it started rebooting randomly, most often when I would be using the stock browser. Half the time it rebooted itself, it would hang and I would have to pull the battery out to shut it off, then start it back up. It was getting annoying and more frequent, and it all came to a head last friday. It rebooted, and once it was back up, it had deleted all of my settings. Luckily it hadn't yet deleted any of my apps or files. So I quickly backed everything up, and performed a hard reset. Then it started rebooting itself about every 2 mins, whether or not I was actually using it. This time it was freezing each time it was rebooting. After a couple of hours of this nonsense, I was able to keep it up long enough to perform another hard reset. It didn't help at all. So now the phone is unusable. I had to borrow a friend's old BB Curve to tide me over until I get a replacement, which I don't even know when I'm going to get. I'm very disappointed that it's having such an issue. It's an awesome phone otherwise, and I'm looking forward to getting that replacement quickly. =(
