White Apple iPhone 4 in transit to U.S. stores this weekend
Regardless, the white version of the phone is expected to boost sales of the model in a year when the next generation iPhone isn't expected until we get closer to the 2011 holiday shopping season. The delay from a summer introduction should give Apple enough time to prepare enough CDMA and GSM units of the iPhone 5 to allow both AT&T and Verizon to offer it at the same time.
The white version of the Apple iPhone 4 had been delayed prior to the launch of the black model. Light leaking out from the casing was a major issue and Apple tried various numbers of coatings before the problem was solved.
