Supposedly, with the iPhone OS 3.1, in addition to being able to send audio/video MMS messages, would come the ability to tether. But I don't think AT&T has turned on that feature yet. I think they're still upgrading their network to handle the data usage.

Yes these apps sound really cool, I hope they hurry up with Tethering. Yea, were with AT&T (USA) and waiting.... I have heard about jailbreaking the iphone and enabling the tether function....
