I cannot do a nandroid backup until rooted, the way I understand it. So, if I take my stock ATT S3 and flash one of these ATT root-injected ROMs ([HOWTO] [ROOT] No Tripping Flash Counter - Updated [ATT / Bell / Telus / Rogers] - xda-developers), I'll be able to do a nandroid backup then. My question is, if I flash one of those ROMs, will my settings, apps, etc be gone? Or will they be in place and my backup will be my current phone, only rooted? Hope that makes sense....
