Ok, I've read the threads out there and it sounds like, for my needs (I'm rooted but on 2.1, no radio OTA update....want to get to leaked Froyo and root), I should go with Ti Backup and ONLY backup 3rd party apps (not system apps). Sound right? Also, Ti will not backup SMS, will it? I have SMS backup but have never tried to restore SMS history with it. I know I have to unroot with RUU and will need to wipe the phone, but it sounds like if I do Nandroid now that I have root, it would only create an image of my ROOTED 2.1, so if I Nandroid > unroot > leaked Froyo > root w/ unrevoked > Nandroid restore ....I would only be restoring an image of 2.1+root over my unrooted 2.2 ... so, I should not do Nandroid and instead stick to Ti Backup. Make sense?
