A report from DigiTimes states that Apple is expected to release three different versions of the iPad in 2011. These will include Wi-Fi, UMTS (3G), and CDMA (Verizon) versions.

Apple will ship about 500,000-530,000 units to channels in January with shipment ratio of Wi-Fi, UMTS and CDMA models at 3:4:3, according to industry sources, citing upstream component makers.

Apple presently ships two distinct versions of the iPad in three different storage capacities (16GB, 32GB, and 64GB). The two current versions include a Wi-Fi only version and a 3G version which supports the AT&T network in the U.S.

Adding a CDMA version would allow the iPad to be sold on the Verizon network in the U.S. as well as other CDMA networks around the world. While mass production will begin in late January, the launch of the next iPad is expected “by the end of the first quarter or the beginning of the second” according to DigiTimes’ sources.
