Apple is optimistic for not just its Verizon iPhone plans in early 2011 but for its regular GSM iPhones as well, part suppliers claimed on Monday. The company reportedly plans to ship five to six million CDMA iPhones between January and March, but has also increased its production of regular iPhones from 13 million to 15 million, giving it as much as 21 million shipments. The CDMA version also wouldn't be exclusive to Verizon as Digitimes has put it shipping in the US and Asia-Pacific.
