The iPhone 3G is twice as fast as the first-gen iPhone, yet only half the price.  You’re probably wondering whether you’ll be able to tether the iPhone 3G (tethering: using it as a cellular modem for laptops - a service AT&T and other carriers offer for many phones on the market) to your laptop.  The short reply is no.  The enlarged reply is no.  Is it AT&T’s fault or Apple’s?  According to AT&T, the ball is in Apple’s court.

Jobs would have showed off the feature during the keynote at WWDC 2008, but he didn’t.  That doesn’t mean it’s not possible.  So Apple flip the switch to enable tethering on the iPhone 3G, it’s possible AT&T will find a

way to charge additional for the option whether you plan on using it or not.  It’s a little too early to concern about that right now.

However according to AT&T spokesman, Mark A. Siegel, who spoke with iPhone Atlas earlier that week, AT&T will not be supporting a PAM plan for the iPhone 3G. The only available notes plan for the iPhone will be the new $30 consumer unlimited info and visual voice mail plan and the $45 business documents plan. The latter is charged when a person makes an enterprise type connection to Exchange or a Blackberry server for mail or messaging. - iPhone Atlas
