I think you can try two things : the soft reboot, and if it does not work, the hard reboot. Don't worry, you can't lose data with these two reboots.
Soft reboot :
1) Hit the three following keys at the same time :
- Right Shift
2) wait 2 minutes for the Blackberry to wake up.
Hard reboot :
1) your Blackberry device is on
2) remove the battery and wait for a minute
3) Put the battery back
4) wait 5 minutes for the device to wake up.
Please tell us if it works for you.
