iPhone 5S and iOS 7 pop up in dev logs linked with Apple HQ

The first tangible signs of the next iPhone have been detected, according to The Next Web, who have cited unnamed developers as the source of the latest gossip.

Apparently, developer logs linked with Apple's campus in Cupertino, California feature new identifiers indicating that the rumoured handset, as well as the firm's next mobile platform update, iOS 7, are indeed on their way.

The mythical handset is currently undergoing testing and is denoted by an “iPhone6,1” tag, the sources claim, which if taken literally could mean that Apple's next mobile offering is skipping the customary intermediary moniker and will instead sport a whole number, meaning the appearance of an iPhone 6 and not an iPhone 5S in 2013.

Apple’s current smartphone iteration, the iPhone 5, is said to have borne the identifiers “iPhone 5,1” and “iPhone 5,2," with the different tags referring to which 4G band is supported by the handset.

The developer log entries have supposedly been traced back to the IP address of Apple’s Cupertino headquarters, adding credence to the rumour.

If the reports prove to be true, Apple’s next smartphone product could be on track for its speculative early-2013 launch and, at the very latest, should arrive in the middle of the year.
