Dual-Mode iPhone 5 Shows Up in App Developer Logs

At least one developer reportedly has found evidences confirming fact that Apple is testing the dual-mode iPhone 5, supporting both GSM and CDMA in one phone, against current App Store apps.

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.
