Rebooting Your Blackberry
Hat tip to the folks at “Blackberrycool.com”:http://www.blackberrycool.com/2005/03/15/00275/ for these tips that give you the equivalent of CTRL-ALT-DEL for your Blackberry:
* If you have a 72xx, 75xx or 77xx then if the Blackberry crashes, you get back by holding ALT+CAP+DEL to reboot the device if you have Blackberry software V3.x or earlier. These are usually Blackberry sold a year or so ago
* If you are using a late model 71xx or 85xx with the BlackBerry OS 4.x or higher then you have to do ALT+CAP+DEL twide. Once will do a short reset and when the buttons come back, hit it again for a full reboot.
* If all else fails, just take the battery out and put it back in again.
