Please help! I'm experiencing the same problem. I was trying to to use the twitter, then my unit froze. I waited for few minutes and it still won't load so I tried rebooting it by removing the battery. (Battery is full charged btw). Then I tried turning it on, but it won't. There's a red light and the blackberry loading is showing up on screen then after 4-5 seconds the unit will die then load again.
