We’re not quite sure what the snag is, but the white iPhone 4, which was previously delayed to an end of July release, is now delayed to the end of the year. Apple had cited that the device was harder to manufacture than anticipated.
It’s unclear if Apple will re-tool the antenna issue that has been plaguing the black variant–and in Cupertino’s words, most other smartphones as well–but it seems unlikely. Many tech sites are hopeful that the white iPhone delays will result in Apple’s part in addressing reception problems that have placed the iPhone 4 release, but at its latest press conference, Apple has stated that it won’t be making any changes to the design–whether those be material changes that will affect the look of the phone or more minor changes like coating the steel band antenna so it doesn’t conduct and fuse together when both pieces come into contact with the human hands is unclear. At this point, unless Apple wants to deal with the over 3 million units sold by altering antenna, it seems unlikely that there will be any changes.
Industry experts have noted in the past that the white coat of paint, in as thin a layer that Apple demands on the glass, would be hard to achieve to get an even layer. The delay seems more likely to be attributable to paint issues and ramping up manufacturing to produce the maximum number of black and white iPhone 4 units for a multi-country global release to meet strong demands.
