Nokia slide 6700 N memory problem

Had the problem, posted the solution here: nokia forum:

I performed the "3 fingers reset method" explained here in French:comment ca marche.

Stop the phone remove the sim card.

phone swtiched off, press the following keys together - all at the same time :

the key [3]

the key [*]

the [green key to pick up a call]

Press shortly the [turn on key] , lift it up again as ssoon as the phone vibrates and the nokia startup tune comes. keep the other three keys pressed until a prompt to change the date comes. My phone was reseted and the anoying memory problem was removed.
