I was making the rounds before really getting into my day when I saw this over at Mobility Site (a regular stop for me).  They cite an iPhone Atlas article which credits an AT&T spokesman with indicating that tethering won’t be allowed for the iPhone 3G (even though it currently is for the iPhone 2G).

…according to AT&T spokesman, Mark A. Siegel, who spoke with iPhone Atlas earlier this week, AT&T will not be supporting a PAM plan for the iPhone 3G. The only available data plan for the iPhone will be the new $30 consumer unlimited data and visual voice mail plan and the $45 business data plan.

This really takes me aback, as this was something that I was looking forward to. I don’t do this a lot (and won’t with the new iPhone), but it is nice in a pinch when something (an important e-mail, post, etc.) HAS to go out NOW and can’t wait until I get off the train.

This is either going to change at AT&T, or people are going to find a way to work around it.  I’d rather not do something like this without permission, however… but when you’re stuck you either have to carry around a spare phone that WILL do it, or figure out a way around the problem.

UPDATE: It was pointed out to me that there is NO official way of tethering your iPhone to your computer, and that is correct. The article at iPhone Atlas does mention a method of tethering your 2G iPhone to your PC; but its a hack, and is NOT sanctioned by AT&T.  Please note that no one at Gear Diary advises doing anything that would violate any agreements users enter into with AT&T or any other carrier.  You attempt something like this at your own risk.
