I've updated to iOS 8.3 a few days ago. And now in iTunes, my iPhone is clearly visible, but when I hit the sync button, it just spins its wheels for a minute and then gives me a message:
"The iPhone "Steve's iPhone" could not be synced because the sync session failed to start."
This sucks, especially when you are about to sync songs to your iPhone and use the best iPhone ringtons. Good news is that there's actually a fix for such problem. Read on to learn details.
