Apple Insider posted a story that anecdotal evidence in support of the long-held belief that Apple's next iPhone will support both GSM and CDMA networks has emerged in the form of an anonymous developer who reports that a new dual-mode device has appeared in app usage logs.

According to Monday's report, the developer's app is being tested by "what is almost certainly an iPhone 5" running iOS 5 and holding "two distinct sets of mobile network codes (MNC) / mobile country codes (MCC)," which are used to identify mobile carriers.

"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," Wauters wrote.
