iOS 5.1 Alludes to iPad 3, iPhone 5 and Apple TV

Apple recently released the beta version of iOS 5.1, a significant update that introduces a set of new features, which is also meant to solve once and for all the iPhone battery issues.

Before discovering what the new update actually does, developers were snooping into iOS 5.1 code looking to find references to certain future Apple products. One such entry codenamed iPhone 5,1 suggests an iPhone 5 with significant upgrades (based on the step-up from 4 to 5), could be on the market in the not too distant future, knocking the new star iPhone 4S off its short-lived perch.

There are also hints at three new iPad 3 devices, which are codenamed iPad 3,1, iPad 3,2 and 3,3; this may be referencing Wi-Fi, 3G and 4G or dual-mode tablets. Previous reports about the next generation iPad point towards a release in spring, probably in March; there has also been some talk of an 'iPad mini'.

A new iPad 2,4 model is mentioned too, maybe a new iPad 2 version available for Sprint subscribers, possibly with LTE or WiMax technology.

iOS 5.1 also hints at another mysterious device, so far nicknamed J33, which many pundits are speculating could be the future Apple TV that has been getting more column inches of late.
