Formatting an S60 device:

Soft Reset (*#7780#): This is a normal reset. It will load the original settings from the phone's ROM. However, it will retain the user's own data. Like images, music, installed applications etc.
Hard Reset (*#7370#): This method completely reformats the C: drive (phone memory). All the user information will be deleted. Like images, music files, installed applications etc. Hence, the phone is set to the default factory settings.
On performing any of above methods of formatting the phone, device will ask you for a security/lock code. Default code is 12345.
