Evidence of a next-generation iPhone model has been found in the latest version of the iPhone’s firmware. Mac Rumors notes that a string in the USBDeviceConfiguration.plist file contains information for a device labeled “iPhone2,1,” while the original iPhone carried the designation “iPhone 1,1” and the iPhone 3G was labeled “iPhone 1,2.” For comparison, the first-generation iPod touch was labeled “iPod 1,1” while the second-generation model is labeled “iPod 2,1” due to its significant hardware differences such as volume buttons, an internal speaker, and integrated Nike+iPod support. The existence of a next-generation iPhone is further supported by the appearance of a device labeled “iPhone 2,1” appearing in a developer’s PinchMedia ad serving reports, suggesting that Apple is currently testing the device for a near-term release.
