iPhone With Dual CDMA And GSM Modes Detected
According to MacNN, an iPhone with both CDMA and GSM modes have been detected. According the original link, Techcrunch, an iPhone was detected using both AT&T and Verizon networks. However, this isn't surprising given the rumors for months that the next iPhone will be able to work on both more networks using one iPhone model - both GSM and CDMA.
Although that was expected, it seems a bit late in the cycle for just such an iPhone to appear. Considering, this should be have seen a while back.
However, such an iPhone does mean that it will most certainly not support LTE. You can't have it both way, apparently.
