Dumb n00b question time -

If I use:

1. Use the backup utility to back everything up
2. Flash my UK Vodafone model with global firmware

Then am I able to restore the backup and get my settings, installed apps and contacts back?

I haven't played with backup and restore so I don't yet jknow what exactly it backs up or restores.

Oh and also, is it going to work from win 7 64 bit? I have ultimate so it's supposed to emulate XP pretty well...
