Yet another White iPhone 4 has been spotted, this time in New York City. This much delayed device has been pushed back due to it being “more challenging to manufacture”… and the actual manufacturing challenge is apparently the home button. According to a couple sources who captured pictures say that the suppliers are having trouble matching colours up. One supplier made the white home button colour and the other made the white front face plate colour… thus causing issues with the colours being off and Apple will not release the device to the public until the product is perfect looking.
