edit:i just read that nandroid backups(made in RA,at least) are backwards compatible. So if you made a backup on 1 .8.0 ,then upgraded to 2.2.1, the backups would still work unless you upgraded your hboot version since that backup was done.

edit,edit: I found a cool app on the market called Wimax Keys Checker that checks to see if your key's are intact...must be rooted : )

very nice app!!! +1
