After some initial confusion following WWDC, an AT&T memo has pegged the iPhone availability at 6pm in your respective US time zone. We imagine this comes down to Apple's meticulous level of control over any monkey business. As such, the magic 6pm launch is likely the result of a next-day, 6pm delivery cutoff by AT&T's distribution agent -- FedEx. You don't think these babies are just going to be sitting around in the stock room do you? So if you happen to see a FedEx guy hovering near an AT&T or Apple store on June 29th... well, be nice, mkay?
