Well finally restored my settings and apps to my new N900 and all seems ok.

AIMED AT NEW USERS
It is worth doing a backup from time to time and store the backup file on your phone memory card, pc or memory stick.
It saved a hell of a lot of setting up, it restored all apps, phone settings even email settings within 25 mins.
The only thing a think i need to setup is the sixaxis controller because my new phone will have a different bluetooth address.

Apart from that all seems ok..................cross fingers.
