You entered an incorrect password ten times and your BlackBerry has been wiped. You now have to reinstall the OS. Simply put, there's nothing left on your BlackBerry. This is a security feature. Imagine you were someone else trying to access your phone. What would they be able to access now? Nothing. That's one of the great points of owning a BlackBerry.
Plug your phone into your PC and open BlackBerry Desktop Software. If you don't have it installed, it can be found at www.blackberry.com/desktop from your PC browser. Once it's installed, plug your phone in and click Device at the top of the software then Restore from the drop-down menu. Choose the most recent restore point and proceed.
I hope that helps you.
