With only a week left into the month of July and no reservations in sight, you should be under the assumption the White iPhone 4′s is further delayed. MacRumors got the confirmation the White iPhone 4s are delayed until later this year:

White models of Apple’s new iPhone 4 have continued to be more challenging to manufacture than we originally expected, and as a result they will not be available until later this year. The availability of the more popular iPhone 4 black models is not affected.

We posted previously that Apple’s manufacturer is the one to blame since they can’t quite perfect the white version’s glass screen.

There’s no confirmed or even estimated date of when exactly late this year these iPhones will ship. If I were you, I’d reserve a black iPhone 4 right now since I might be waiting for forever to get a white version.
