Registration logs from an anonymous app developer suggest that the next gen iPhone will feature a dual mode cell chip capable of operating on both CDMA and GSM networks. This would allow Apple to produce a single device instead of two slightly different models for AT&T and Verizon, and could potentially be used as a “world phone”—since the device could switch between network bands as needed overseas. A dual mode iPhone could also mean that the handset is finally ready to make its way to Sprint.
The logs show that the app has been briefly tested by a handful of people using what is almost certainly an iPhone 5, evidently running iOS 5, sporting two distinct sets of mobile network codes (MNC) / mobile country codes (MCC). Those codes can be used to uniquely identify mobile carriers.
Sure enough, some registrations for the app – which the developer also asked not to be named – were logged from a new Apple device, using the MNC/MCC codes from both Verizon and AT&T.
