Okay - so I am not usually interested in iPhone rumours and predictions. Everyone has one and they are usually baseless . But here is one from Forbes: The next iPhone may actually not be that exciting - only a dual core processor, curved glass, NFC functionality (yawn!). BUT here is the interesting tidbit: it could work on ANY wireless carrier OR NONE AT ALL. Imagine walking into an Apple store, walking out with an iPhone5 and using it on any wireless carrier (since the phone has both CDMA and GSM radios). Or maybe you prefer to use it only through VoIP services. Now that is different.
Of course Apple is going to suggest that this is all new and innovative BUT don't forget that Google tried to bypass the wireless carriers with their NexusOne. The problem was that their initial offering worked only on TMobile and people don't really care for spending $500 bucks on a phone if you can't hold it in your hand.
Everything said and done, if this does indeed happen, it will be really exciting and game changing. Maybe not so much for the techies (yes! yes! the quad core iPhone should come out sometime in 2013) but for anyone who is interested in mobile strategy and business models.
