iTunes won't sync my iPhone/iPad
I have the iPhone 4. I am purchasing the iPhone 5 tomorrow. However, I have not been able to sync my phone or iPad in months. I get an error message saying either 1. the Apple Mobile Device is not up-to-date or 2. I need to reinstall iTunes as the 64-bit version. I've already uninstalled/reinstalled iTunes multiple times. I really need it to start working so I can restore all of my music/apps, etc. on my iPhone 5. Any help would be greatly appreciated!
iPhone 4, iOS 6
