Apple already appears to be testing its next iPhone and mobile operating system.
Multiple developers of Apple apps say they have begun to see references to "iPhone6,1" hardware running iOS 7 in their app data usage logs, according to the Next Web.
App data usage logs help developers identify the kinds of devices and operating systems that are using their apps. The current iPhone -- the iPhone 5 -- is identified with either an "iPhone5,1" or "iPhone5,2" designation.
Adding to the intrigue of the new device and operating system showing up on usage logs are their IP addresses, which appear to be originating out of Cupertino, Calif., which happens to be Apple's hometown.
While it's intriguing to discover that Apple might already be testing new products, the logs don't reveal anything about new features that might be coming.
At most, the logs only show that Apple may be working on its next smartphone and its software, which some analysts believe will be released later this year.
