How can I perform a hard reset on my Symbian phone?

note this will delete all personal information, settings and applications in the phone, so only do this if your absolutely sure you haven't anything stored on the handset you might later want. Also, your phone will not speak after the hard reset since you will have to reinstall talks or mobile speak which ever you use.

The procedure for the hard reset is:
1) Make sure phone is fully charged and switch it off.
2) Press simultaneously the green "call" button, '*' "star" and '3', and keep them down.
3) With those 3 keys down, switch the phone on.
4) Only release the 3 keys when the phone shows signs of life such as the Nokia logo or the language.
