im a new blackberry user and my 7520 that i bought off of ebay has been giving me trouble with my text messages so i wanted to see if totaly restarting the phone would help
can you help me please
Options / Security Options / General Settings / Menu / Wipe Handheld will remove all your personal information and restore the 7520 to factory-out-of-the-box condition, without changing the OS you have loaded.
There is a way to delete the OS as well. If you feel you need to do that, be sure you can find a compatible OS and download it before you start. Then follow BMcClure's procedure in my sig.
