So I have had my blackberry curve 8310 since December 07 and everything was working fine and then one morning I woke up and it kept trying to reboot itself and it would keep going to the hourglass and then it would cut itself back up and go back to the hourglass and it keeps doing this. It only "loads" for about 15 seconds and then cuts off. I have tried EVERYTHING. I've taken the battery out for hours/days and nothing seems to work. Someone PLEASE help!

I read some where that it could be a media card. If you have one remove it. If that doesn't resolve the issue try this:
