Need to delete all from blackberry
 

I just received a replacement unit from Cingular (8700c). Before i send the old phone back, I want to delete everything (calendar and contacts) that is on my phone as it was not save to my simcard. I thought I remember seeing a "return to factory settings" at some point but can not find it anywhere. Thanks in advance for your help.

You can always type in the password wrong 10 times in a row if you have security turned on this deletes all the data.

That will work, as will Options -> Security Options -> General Settings - click the trackwheel and select "Wipe Handheld"

thank you
