Sorry i typed my question in the wrong box, but i found the right one now so here goes...

i got a blackberry curve yesterday and my brother was playing on it and has some how put a code onto it so i cant get into it...

when i try to get onto my menu etc it says 'devise is locked' and gives me the following options:
unlock, emergancy call, and cancel..

does anyone no how i can get this lock removed please help!!

and when you press unlock, what happens?
it asks then for a password?

Sounds like he set the password. If you don't know it, you can't use it. Type it in wrong ten times, and it will do a "wipe handheld", which resets it back to factory defaults, erasing any data you have.
Since you've had it one day, you probably don't have much data to lose.

Backup regularly and don't let people play with your BB.
