It seems Apple and AT&T are in talks regarding adding a tethering option to the iPhone. One user emailed Apple to complain about the lack of that feature, particularly considering it is offered on most other smartphones for $30/month.

Supposedly, Steve Jobs replied and said:
We agree, and are discussing it with ATT.

Interesting. AT&T actually does offer a tethering option for their other smartphones for, you guessed it, $30 a month. But the iPhone has been excluded from that. For those who don’t know, tethering is a feature that allows a user to connect to the Net through their cell phone. In effect, turning their phone into an Web connection for a laptop. As you may remember, Nullriver’s Netshare was pulled from the App Store recently considering it offered that very feature.
