I think it is safe to assume there will be some fairly major design changes with the 3G iphone, if you go to Vaja's website and click on Apple and then phones they have an email list already up for the 3G iphone. Of course, if the physical specifications of the 3G iphone were not changing then they would not be releasing new cases, but rather just keeping the old one. As an accessory vender, Apple would have already given Vaja the design specifications of the new phone so that they can create an accessory for it, thus it is pretty safe to assume that the new Iphone may be longer, shorter, lighter, or totally different than the current version-whatever the case (pun intended) the 3G iphone will not be identical to the current 8/ 16 gig models.
