iPhone 5 CDMA and GSM turns up in app tracking
Repeated references to a dual-mode iPhone 5 were borne out late Monday after a developer mentioned that it had been showing up in app logs. A small batch of users have been tracked while running two carriers. One of those seen by TechCrunch attached itself to both AT&T and Verizon, which wouldn't be possible on the current models.
It's possible to fake the carrier ID and similar elements on jailbroken iPhones. Creating two simultaneous IDs on one phone would be difficult, however, if not impossible without the requisite hardware.
Apple is widely expected to be using a Qualcomm cellular chipset that would give it both CDMA and GSM, along with matching 3G, without having to have separate phone models. The step would let Apple go back to making just one core model. It would also give Verizon subscribers true world roaming support so that they're not limited to the US and a handful of countries where CDMA is widespread.
Many see a dual-mode iPhone as necessary to help Apple move to even more carriers than it does now, particularly in countries where CDMA is only one option and GSM is equal or more common. It has already dropped hints of support for Sprint and T-Mobile, and it might also support China Telecom, Japan's KDDI, and Indian carriers such as Reliance or Tata.
