I have only had my blackberry 8800 for a week I put a lock on it so unwanted people couldnt see my information, however after doing so I left my blackberry when I went out. One of my family members had tried to unlock the password therfore locking it and deleting my information from the blackberry.
This is a real problem ive lost all the packaging because im moving soon so I cant look on the manual. Now when I open the phone up it says jum error reset.
Is there any way I can start using it again or reseting the password.

I am completly unhappy over this can somebody please help me I would be more than greatfull
