I have just reflashed my N900 to PR1.2.

As I had so little rootfs space I used NSU and as expected it reset much of my config. I did backup many files but not all of them.

Now I need to setup all my wlreless network WPA keys again, and I am wondering if there is a file I can restore (if it was one I backed up), to save me doing this?

Any ideas?

Thanks.

When you ran backup app you had few options to tick -- applications, bookmarks, settings and communications & calendar.

Your wireless settings are atored in either settings or comm&calendar. I belive it's later. Restore your backup and (almost) everything will be back.
