It’s literally destroying, expunging, obliterating, eliminating (you get the idea) EVERY trace of its owner’s presence.

It removes all phone book entries, all calendar entries, all call logs – literally making the phone seem brand spanking new… Traces of the phone being used will be gone (with the exception of the memory card – which you’ll have to format manually)

And why would I want to do that?
It’s like reformatting your PC / MAC. Sometimes you feel like it needs a bit of spring cleaning but you’re just too darn lazy to clean it – so why not WIPE it completely clean? Here’s how you do that on a Nokia N95.

Not sure if it works for other Nokia N-Series mobile phones but it’s worth a try

Behold – the self-destruct code – *#7370# (don’t panic the phone will still
work fine after this – it’s just that user data will be wiped-off)

Enjoy!
