Note:
Format phone restores phone to as if it was out of the box. Retains firmware version and operator Variant changes but wipes all applications you have installed. Does not format the memory card so any apps on there may reinstall once powered back up again.

Another way to format some symbian phones: Power off phone. Press and hold Green, * and 3 and keep them held whilst powering on and for a few seconds after.

Factory Reset resets all settings to defaults but keeps any applications you have installed and photos etc. Both need the Security code, which, by default, is 12345.
