"iPhone cannot be synced because there is not enough free space to hold all of the items in the iTunes Library (additional space required)."
My iPhone4 is, after only 6 months of usage, is now saying there's not enough free space to take photos, sync to iTunes, and other things I don't understand. I tried using the the iPhone help and iTunes help and I couldn't figure it out. I used to be tech savvy... but apparently not when it comes to Apple stuff....
iPhone 4, iOS 6.1.3
