Yesterday at Goldman Sachs' Communacopia XVII conference, AT&T's chief technical officer John Donovan stated that iPhone 3G users have used much less data on the network than expected.

No explanation was given, but aren't the reasons pretty obvious? All of the connection issues along with 3G reverting over to the Edge network is what I'm guessing. Donovan later went on to say that the iPhone's 3g data usage is still "relatively higher than any other phone on the network". He also went so far as to downplay that AT&T just may have underestimated the network demand following the iPhone 3G launch on July 11th. He did say that improvements made since then were all planned to help meet the anticipated demand. Sorry folks, I'm not buying that one. How about you?

The last good bit of information came regarding AT&T's plans for 4G: it's coming and testing will begin sometime in "2010" with the service following soon there after. AT&T will be not be the first to toy with 4G but rather "leave early adoption to other companies". (Namely Verizon who has slated launch of their 4G network the same year.)
