Taiwanese trade publication Digitimes reported Monday that sources with Asian component suppliers claim Apple upped its first quarter manufacturing output for iPhones to approximately 21 million units, a two million units increase from the previous estimate.

If true, the figure would represent the annualized rate of 84 million iPhone units, or nearly twice the 47 million iPhones estimated for the entire 2010, which would beat all previous Wall Street estimates.

In addition, the publication also wrote that the talked-about CDMA version of iPhone suited for the Verizon network is due some time during the first quarter of next year:

The first-quarter shipment goal for WCDMA iPhones has been adjusted from 13 million units to 14-15 million units, the sources said. The shipment goal for CDMA iPhones, which will be launched in North America and Asia Pacific in the first quarter, is set at 5-6 million units, the sources added.

Apple’s long-time manufacturing partner Foxconn (also known as Hon Hai Precision Industry) is said to be the primary maker Verizon iPhones, although Pegatron Technology should participate in the handset’s production as well.

Digitimes previously asserted that iPad 2 is hundred days away from shipping. Another publication last week quoted insiders claiming that device features include a slimmer design, two cameras, and a wide-band speaker, while Reuters named iPad 2 suppliers.
