Apple released yesterday the beta version of iOS 5.1, the first major update since the release of iOS 5 in October.
Soon after its release, developers have found intriguing codenames suggesting that much-awaited Apple products will soon appear.
Thus, the iOS 5.1 code contains references to the iPhone 5 and 2 iPads, internally named iPhone 5,1, iPad 2,4 and iPad 3,3, respectively.
Given that the iPhone 4S was previously listed internally as iPhone 4,1, this reference to iPhone 5,1 could cite the next-generation iPhone model.
The code also lists a new device called J33, which many believe is the future Apple TV box that connects the TV set to the Internet.
The data doesn’t give precise details regarding new devices, but it can help form an idea of Apple’s future release schedule.
