Dual-Mode CDMA/GSM iPhone 5 Now Being Tested by Apple?
It appears that either Apple engineers or executives, or carrier executives, are beginning to test an iPhone 5 device with dual-mode CDMA and GSM radios, which would make the next-generation iPhone a world-phone model. By offering a multi-mode GSM and CDMA device, Apple could offer 1 device for either AT&T or Verizon Wireless, with the former operating a GSM network and the latter utilizing a CDMA network in the U.S. The move would allow Apple to simplify its product line while being able to simultaneously reach customers on both network technologies.
According to TechCrunch, a developer who does not wished to be named but did offer proof confirming the fact, revealed that a single phone carrying two different carrier IDs simultaneously was tracked in his app logs.
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.
The same device was accessing the app through both AT&T’s and Verizon’s network, it appears. This scenario would not be possible with today’s iPhone. Though the CDMA version of the iPhone 4 offered through Verizon Wireless does contain a global Qualcomm chipset, that phone model lacks access to a SIM card for which to access a GSM network, limiting the world phone chipset capabilities.
