"factory reset" on Nokia 7210?

[8bit]

hey all

i replaced my 7210 recently with a 6680 and want to give the old handset to a friend. The memory is full of old texts, phonebook entries and a load of other stuff i don't want to pass on with it. Is there some way of doing a "factory reset" or similar, returning the memory to the state it was in when I got it at first?

TIA

'Factory reset' using data cable on the Nokia 7600 doesn't erase anything on the phone, it should be similar with the 7210.

Erasing everything manually is the best way..
