Developers at Apple are said to be viewing reference hardware for what has been logged as the “iPhone 6,1” which will run on iOS 7.
From The Next Web:
Currently under development, traces of Apple's new iPhone and iOS software have begun surfacing in app usage logs. Developers have contacted The Next Web to share references to a new iPhone identifier and the next big operating system update for the smartphone and tablet devices: iOS 7.
One developer showed us that Apple has been testing hardware relating to a new ‘iPhone6,1′ identifier, powered by a device running iOS 7, which is expected to be released by Apple in the middle part of this year.
Apple's current flagship, 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.
From the developer logs that we have seen, the app requests originate from an IP address on Apple's Cupertino campus, suggesting that members of Apple's software development and app teams are compatibility testing some of the more popular or well-known applications already on the App Store.
Although OS and device data can be faked, the unique IP footprint leading back to Apple's Cupertino campus leads us to believe this is not one of those attempts.
As of now there is no public information regarding software features, but developers began working on the new iOS 7 towards the end of last year.
Upon its release late fall, the Apple sold 5 million iPhone 5 phones in just three days.
