Apple has begun testing another new version of the iPhone and the latest iteration of their iOS operating system, according to The Next Web.
iPhone application developers have reported finding traces of a new iPhone in their app usage logs. While the current iPhone5 uses the identifiers "iPhone5,1" and "iPhone5,2," the identifier spotted by developers was "iPhone6,1," leading them to believe that a new iPhone was being tested, according to The Next Web.
Usage logs track which devices and which operating systems are using the apps; the IP addresses used by each device are logged as well.

According to certain app developers, the IP addresses used by the devices originated from Apple's Cupertino headquarters, wrote The Next Web's Matt Brian.
While operating system and device data can be easily spoofed, the unique IP address used by Apple's Cupertino headquarters is further evidence to suggest that these devices are indeed new versions of the iPhone, according to The Next Web.

However, it remains unclear what phase of testing the new device is undergoing or if the device will be released in the near future.
Considering Apple CEO Tim Cook's pledge to "double down on secrecy" last May, it's possible the new iPhone identifier is a spoof by Apple employees, as well.
