Besides hints of turn-by-turn GPS directions, the beta 2.1 firmware also reportedly contains references to an unreleased iPod Touch known as “iPod2,1″, according to iPhoneAtlas.
The current iPod Touch carries a model designation of “iPod1,1″. iPhone readers may remember that the original iPhone is known as “iPhone1,1″ while the iPhone 3G is known as “iPhone1,2″. It should be noted that these model numbers don’t appear to change for storage differences alone. The original iPhone saw 4GB, 8GB and 16GB sizes but shared the same model number. Only when the iPhone 3G introduced new features, such as a GPS and 3G chipset, did the model number increment.
