TUAW reports today that sources who have inspected the iOS 5 betaís USB device files have found references in the files to two iPad 3 models (iPad3, 1 and iPad3,2) and two iPhone 5 models ( iPhone 4,1 and iPhone 4,2), but strangely no reference to iPod touch 5. TUAW explains that the iPhone 5 is considered 4th generation because the iPhone 3G was 1st gen. Of course the mention of these devices is no guarantee that they will be released at all even, but itís still a possible indication that the iPad 3 could be on its way sooner rather than later. TUAW notes that while the iPad references are new to iOS 5, the iPhone 4,1 and iPhone 4,2 references first appeared in the iOS 4.3 betas back in January. The lack of an iPod touch 5 reference could be another clue that the iPhone 5 will be released this September, as this is when Apple would usually launch a new iPod touch. If the lack of a reference in the files means that there will be no new iPod touch this September, itís possible that this is because Apple is launching another product in that timeframe instead, which is almost certainly the next iPhone.
