How do I downgrade from ios7 to ios 6.1.4 for an iphone 5 on att? I believe that ios7 is ugly and much too 2-dimentional that has lost apple's innovative appeal for me. Before the "upgrade to ios7", i created a standard sync backup on my computer through iTunes. Does this backup include the operating system (ios6.1.4) and if it does, simply restoring the phone through iTunes will solve my problem where I can ditch this ios7? Thanks for helping!
