I am new to Apple and came here because of the USB sync between iOS and OS X. My iPhone 5 shipped with iOS6.x and all worked well, until he updated to 7.x. After the update, Notes could only sync via iCloud. In South Africa with insanely expensive data., limited "cloud cover" and unreliable mains power supply, direct sync is essential. Then an update to 7.05 also killed much of wifi functionality including sync. I now consider updating to 7.1 but will this cure the wifi sync issue? What else will break when I upgrade?
