My Blackberry has a frozen screen. What should I do?

Try a Soft Reset.  If that is unsuccessful, try a Hard Reset.

How do I perform a Soft Reset?

From the handheld, press the ALT + CAP + DELETE keys at the same time. You will not lose any data during this process.

How do I perform a Hard Reset?

From the handheld, locate the RESET button on the back of the device near the bottom. If you do not see the reset button, check under the battery cover. Look for a small hole with a label that says RESET. Using a pin or paper clip, press the RESET button. In some cases, there will be no reset button at all.  In this case, removing the battery for 30 seconds will reset the device. The device will restart. You will NOT lose any data during this process.
