I am confused. The information on iOS 8.0.2 says it is only 1.1 GB. It also says I need 5.9 GB to install it. I have only 1.2 GB available, having used 11.9. In order to install the new operating system I will have to delete ever app that I have, and that will still give me 3.350 gigs plus the 1.2 I have now, not enough to install the new OS. (megabytes not converted exactly to GB, but close enough to prove the point.). What am I missing?
