Maps, maps, maps. For years, Apple used Google Maps but has fallen out of favour with the search turned mobile giant following a string of lengthy lawsuits targeting the rival mobile operating system. Blame the patent system or those who abuse it? Nobody knows.
Google recently announced its own map improvements; likely preempting Apple's own upcoming pitch to developers. Apple will probably include new 3D technology along with step-by-step directions and other bits and bobs for software makers to play with.
Twitter grew massively following iOS 5's release. It was the first social network to be included with Apple's mobile operating system, despite Facebook having more than six-times the users at the time of its release.
Following Tim Cook's comments that users and developers should "stay tuned" regarding Facebook integration, iOS 6 could include tight Facebook integration just as Twitter was in iOS 5. It would make sense: Apple has to cater to its users and as the vast majority use Facebook, it makes sense to embed it as part of the software.
Apple's App Store -- where all iPhone and iPad applications are installed from -- is due for a lick of paint. Apple bought Chomp in March suggesting a possible integration of the recommendation software among other features. Beyond all else, it's one of the main features of iOS and could do with some sprucing up. It may include improved search function.
