Apple isn't just preparing for new iPads and Apple TVs with iOS 5.1, there's a new iPhone on the block too. Code strings from within the new beta of Apple's mobile OS have revealed an iPhone 5,1 codename, which falls right in line with the company's internal numbering scheme and represents the first evidence of the inevitable iPhone 5's arrival. Of course, some basic software support in a beta isn't exactly the most reliable of predictors as to how far out a device launch may be, but at least you now know that Apple's laying the foundations.
