Somewhere in Cupertino, Calif., the next-generation iPhone and iOS are being tested. We know this because developers have seen app usage logs indicating as much, according to The Next Web.

The so-called iPhone 5S and iOS 7 are still months away from being launched to the public. However, both are alive and well behind closed doors. Usage logs for some apps are showing a new ‘iPhone 6,1’ identifier plus traces of iOS 7.

The iPhone 5 “bears the identifiers ‘iPhone5,1′ and ‘iPhone 5,2′ depending on the LTE model of the handset and the 4G bands on which it operates.”

The logs have been tracked back to an IP address on Apple’s campus. This suggests that Apple’s software developer and app teams are compatibility testing some apps already in the App Store.

The next version of iOS 7 will likely arrive at Apple’s Worldwide Developers Conference this summer. The seventh-generation iPhone could be unveiled around the same time. Recent rumors suggest that the next iPhone will launch in early June in multiple colors and with NFC compatibility.

Apple’s next mobile operating system will be the company’s first not developed by Scott Forstall. Apple’s former senior vice president for iOS was fired in October.
