I went to unlock my phone after not having used it for several hours and it was at the start screen for set up. I have lost all of my apps, pictures, contacts, etc. I am, quite frankly, pissed! Has anyone else experienced this and what caused it? Also, if this is a security issue, why wouldn't you ask to back up before just restoring. Seriously, I switched to Verizon to avoid this type of mess.
