Now that Apple has confirmed the existence of a Verizon CDMA iPhone 4, we can look forward for the iPhone 5 to be support both CDMA and 3G GSM at launch thanks to a dual mode Qualcomm chipset.
Rumours about a GSM/CDMA chipset for the iPhone surfaced last year when Digitimes mentioned that Qualcomm was in talks with Apple to use hybrid CDMA/GSM solutions in its iPhone handsets.
Chinatimes also reported in September 2010 that the switch in baseband hardware from Infineon to Qualcomm may have already taken place as the company is the inventor of CDMAone, CDMA 2000 and holds key patents in W-CDMA.
Launching a CDMA/GSM iPhone 5 model means that Apple will be able to serve many more users from day one and reduce costs by using the same components for CDMA and GSM markets.
It also opens the gateway for a more global launch in June 2011 with China and India being two of the biggest CDMA markets in the world, serving hundreds of millions of customers.
The fact that Apple could choose Qualcomm to supply the blueprint for the next generation Apple A5, a shift from Samsung's Hummingbird family to the Snapdragon one. Hence there's even a slight chance that the A5 may integrate the baseband hardware, GSM/W-CDMA Transceiver, Wi-Fi and others.
