iPhone 5 and more iPad 3 show in iOS 5.1 beta
More discoveries in the iOS 5.1 beta have found Apple's first reference to the 2012 iPhone and to more 2012 iPad developments. Filippo Bigarella has shown a reference to an "iPhone 5,1" in the beta code. As with past models, the next iPhone is being considered a major revision rather than a minor upgrade.
Also mentioned was "iPad 3,3." While iPad 3,2 was already known, it points to Apple possibly having the same three-model iteration as it does now, where one core Wi-Fi version exists along with two cellular editions. With the iPhone 4S now dual-mode, it's possible the split won't be between EVDO and HSPA but instead between 3G and 4G.
Presences in code can still leave several months or more before releases, and occasionally don't lead to products at all. With the iPhone already showing up, though, it's more likely that Apple is aiming to bring the 2012 iPhone release back towards the summer rather than repeat the move to a fall update.
