One of your applications is corrupted. You should reload the OS. Go to the FAQ section at the top of the forum for more info on using one of the available programs.

First thing is to wipe off everything that is still left on the BB..

How do I wipe the BlackBerry using Jl Cmder? - BlackBerryFAQ

Then reload the latest 8700 OS - How do I wipe the BlackBerry using Jl Cmder? - BlackBerryFAQ

Good luck.
