Sources for TUAW have discovered hints towards two future iPad 3 models in the latest iOS 5 firmware, in the form of iOS system files that reference “iPad 3,1″ and iPad 3,2” This numbering indicates a model of iPad that has not yet been released.
There are also two mentions of future iPhone models which were already known from previous firmwares. It’s important to note that model numbers in the firmware do not mean the items will become a shipping product soon (or ever, for that matter). One such example is iPhone 3,2, which was discovered in previous firmware, but never released as a product.
We’ll know for sure in the upcoming months, but until then the hints and rumors will unfortunately have to suffice.
