The current iPhone 5 shows up similarly as iPhone 5,1 (and iPhone 5,2 depending on what LTE/4G abilities each model has), so it stands to reason that the next iPhone will follow suit.
The new version number for iOS is a little less surprising - the identifier iOS 7 doesn't shock us although hopefully its vastly improved battery management will.
Unfortunately, although it seems Apple is testing the new soft- and hardware already, there are no clues as to what upgrades we can expect to come out of Cupertino.
If past experience is anything to go by, we may get a bit of a look at iOS 7 at WWDC in June 2013.
The iPhone 6, meanwhile, is more likely to see a September release date as its older be-fived sibling showed up in Autumn of 2012 although it's possible that Apple will whip the new handset out in June instead - it does like to keep us all on our toes.
