I'm having two problems right now. I have an iphone 3gs on version 3.1.3 and the latest version of iTunes. Running Windows 7. 1. When I plug my iphone in iTunes it gets stuck on the "Verifying iPhone" step every time (it says "could not sync, required file not found"). I've rebooted, hard rebooted the phone, etc, but it always freezes. 2. I have recently put a fresh install of Windows on my PC. As I understand it, if I sync my phone to my iTunes library (assuming I can get problem #1 fixed) it will delete everything on my phone. How do I get everything from my phone into my iTunes library, or add stuff from my library onto my phone without deleting what's already on there?
