Frozen how? You can't open it ? Blackberry can do this sometimes if you drain the battery completely.. you must leave it plugged in until opens. Or, you can try a hard reset doing this:

1. Perform a hard reset to wipe all data from the BlackBerry Classic.
2. Open BlackBerry Link on your computer.
3. Connect the device to your computer using the USB cable.
4. Select your device on the left pane.
5. Go to "Back Up & Restore" > "Factory Reset" (Windows) or "BlackBerry Link" > "Preferences" > "Reload" > "Reload" (Mac OSX).
