Fifth-gen iPod touch reference found in iOS 5.1 build

Code pointing to an updated version of the iPod touch has been found in an internal iOS 5.1 build, according to a new report. 9to5Mac reports that references to an “iPod5,1”—the fourth-generation iPod touch is referred to as “iPod4,1”—were found inside a file which was contained in an internal build of iOS 5.1. As noted in the report, the iPod touch was the only iOS device that didn’t receive an update last year, and also regularly accounts for more than half of Apple’s iPod sales on a quarterly basis. The report also claims that Apple is testing a new version of the iPhone with 1GB of RAM, and that the new phone will not sport a design similar to that of the iPhone 4 and iPhone 4S; the prototype is said to be running a variation of the A5X chip found in the third-generation iPad.
