No tethering for iPhone 3G - The Unofficial Apple Weblog (TUAW)
Over at iPhone Atlas they're reporting that AT&T is not planning to offer a tethering option for the forthcoming iPhone 3G. Right now AT&T does offer the option for many of their 3G phones, which allows you to use the phone as a cellular modem on a laptop as part of a $65/month data plan. According to an AT&T spokesman, however, no such Phone-As-Modem plan will be offered for the iPhone 3G.
