BusinessWeek is reporting that Piper Jaffray has found that every one of the 20 Apple stores around the country they called are out of iPhones. That is almost certainly an indicator that more are on the way, VERY soon. (Apple loses big bucks every day they are sold out.)

Furthermore, Gizmodo quoted AT&T's Mobility CEO saying that within "months", all AT&T smart phones would be 3G, including the iPhone.

This could mean a minor revision is imminent, to be followed by 3G phones later, OR it could mean that the AT&T bigwig didn't want to show his entire hand, and that the 3G phones are actually right around the corner.
