PC World weighs in on all the rumors about the new features and a release date for the updated iPhone. They believe that with the SDK (Software Development Kit) and support for enterprise emails (multiple email deletes at last!) the lack of 3G coverage in the US is going to quickly become an issue. Right now AT&T has coverage in some major metropolitan areas but the timing to expand that is anyone’s guess. The US continues to play catch-up. The original iPhone hasn’t sold well in Europe because 3G has been the standard there for years.
