Apple is planning to start making CDMA compatible iPhone models in December.
CDMA compatible iPhones will be able to be used on Verizon Wireless's mobile network.
According to AppleInsider, analyst Jeffrey Fidacaro, of the Susquehanna Financial Group, said in a note to investors that Apple's hardware partners have confirmed that the company will begin manufacturing 3 million CDMA iPhones in December.
He added that Apple has plans to launch the device in January next year.
As far as the current quarter goes, Apple will be manufacturing around 18.2 million to 18.4 million GSM only iPhones, more than the figure expected by investors.
Fidcaro predicted that Apple will sell around 11.6 million iPhones in the fourth quarter of 2010, a 39 per cent rise from the 8.4 million handsets sold in the previous quarter.
He wrote: “We expect the September 25 launch of iPhone in China and Apple's target of making the iPhone available in 88 countries by month end to aid results in 4QFY10. Our checks show that Apple is still struggling with yields on the mass production of the white iPhone 4.”
