Title says it all... almost. Due to technical issues with my phone, I got a replacement X mailed out to me. Now I'm going through the process of switching over. Not much set up on my current phone so im not backing up anything, but should I do a factory reset before sending my phone back? I don't want any info of mine finding its way out and I'm curious if its suggested to do this before sending a phone back. It couldn't hurt the process could it? Thanks!
