AT&T, following the the reversal of their no-VoIP-over-3G policy, still has nothing new to offer with regards to iPhone tethering. Quotes the Wall Street Journal:

An spokesman for the wireless carrier, however, said that tethering remains unavailable and stuck with the company’s prior statement: “Whenever we offer new features, we want to offer the best possible customer experience. For tethering, we need to do some additional fine tuning to our systems and networks so that we do deliver a great experience.”

While international iPhone users have been able to connect their computers to the internet using the iPhone's 3G network, via Bluetooth or USB tethering since the launch of iPhone 3.0 in June, for US iPhone users, no news remains bad news.

Then again, if you're already complaining about poor AT&T signal, probably the last thing you want is every iPhone user on your tower trying to suck down 5GB of torrents... right?
