My phones keyboard adhesive has come loose so I'm going to go up to the vzw store and swap it out. First, my phone is rooted so I need to unroot my phone first, since that voids my warranty, right? Is this an easy process? Second, on my new handset, if I do a nandroid restore, will it return my phone to the state that it's currently in, assuming I make a new backup? If so, where are the nandroid backups located, and can they be copied to the pc? Third, are there any apps that automate the process? I wouldn't be opposed to paying a few bucks to make this easier. Anything else I should know? Thanks in advance.
