Apple's iPhone 6 and iOS 7 have been spotted in app usage logs by developers.

Developers told The Next Web that references to a new iPhone identifier 'iPhone6,1', which is being powered by iOS 7, have begun surfacing in their app logs. The new iPhone and iOS are expected to be unveiled by Apple later this year.

The iPhone 5 is identified in app usage logs as 'iPhone 5,1' and 'iPhone 5,2' depending on which 4G LTE it uses, so the new 'iPhone 6,1' identifier is believed to be Apple's next generation model.

As noted by TNW, OS and device data can be faked, but the 'iPhone 6,1' has been traced back to an IP address in Apple's Cupertino headquarters, adding evidence to the theory that Apple is testing its seventh generation iPhone and the seventh iteration of its mobile operating system on popular apps in the App Store.

It's believed that Apple began working on iOS 7 towards the end of 2012, and that the company will soon finalise the features that we will get when the new software is released this year.

Apple has been known to unveil the first seeds of its new versions of iOS at its annual Worldwide Developers Conference (WWDC), which usually takes place in San Francisco in June.

It has been predicted, however, that Apple could also be gearing up to release the next iPhone, dubbed iPhone 6 or iPhone 5S, at WWDC this year, as it begins its rumoured biannual product cycle.

During 2012's WWDC, Apple introduced iOS 6 complete with its new mapping service, alongside the Retina MacBook Pro and more information about OS X Mountain Lion. iOS 6 and the iPhone 5 were released to the public in September.
