Pandav, developer of the iPhone application iBART [App Store, $1.99 / Free], claims to have spotted an unreleased iPhone in their app’s analytics, showing up as “iPhone3,1″ in the data collected by Pinch Media. This is the first spotting of a device with that internal identification number “in the wild”, leading them to believe that it is the next generation of iPhone. If genuine, it could mean that Apple has begun field testing the next generation of the device.
