Can't sync iPhone (IOS 7) to iTunes 10.6.3 (G4 PowerBook)
I have an iPhone 4 which I upgraded to IOS 7 a couple of days ago. My computer is a G4 PowerBook running OSX 10.5.8, which won't upgrade past iTunes 10.6.3 so I upgraded to IOS 7 directly on the phone. It turns out that wasn't too smart. I discovered today that I can't sync my iPhone to my computer now and that I also can't downgrade my iPhone back to IOS 6.1.3 anymore. So, it seems that since I can't downgrade my IOS or upgrade my iTunes I can't sync my iPhone anymore. No music, pictures, contacts, calendar, etc. Is there any way to solve this problem without buying a new computer?
