I had an 8130 and have just switched to an 8330. I gave my 8130 to my daughter and was wondering how I reset things back to default so that I can remove all my contacts etc.
Options / Security Options / General Settings / Menu / Wipe Handheld will remove all your personal data and 3rd party apps and return your phone to factory-out-of-the-box condition, with the exception that it won't undo an OS upgrade.
