DigiTimes is reporting that orders for CDMA iPhone 4 units assembled by Pegatron have been cut in half — with only 5 million devices being manufactured in the initial 2011 order, down from 10 million units. Pegatron just this week reported a net loss of $19 million for the first quarter of 2011, which is a historical low. Over 3 million CDMA iPhone 4 handsets have been manufactured and shipped, and it looks like Apple is comfortable with selling around 1 million CDMA iPhones a quarter — until the much-rumored dual CDMA/GSM iPhone 5 is available in September.
