I'm scared to reformat my PDA (XDA Exec) as I spent £660 buying it just a year ago. Fine this isn't the most I've spent on a phone, but you can see that I don't want to waste my money.

I need to know if I can (freely if possible) download Windows Mobile 6 for my XDA Exec, I'm scared that the keyboard or video calling will stop responding as drivers aren't installed. Also I've got one which does have all of that, but does not support Windows Live, so I need that too.

Basically, I need:

Windows Mobile 6 Professional with all features to work on the XDA Exec
