AT&T's plans for the iPhone start at $70 per month for voice and unlimited data, including e-mail and Web access. But there's some talk of AT&T possibly lowering its prices.

"I think they might offer a light version of the unlimited data plan," says Roger Entner, a telecom analyst for the Nielsen Company. That may mean the overall cost for consumers on AT&T's base plan may be closer to $60 per month, he says.

It's also possible that AT&T may start to charge some new fees for services like tethering -- the ability to have the phone function as a modem for a computer.

Kent German, senior editor for CNET, says he and other iPhone users were disappointed to learn that tethering is still not yet available for the iPhone through AT&T.

A spokesman for AT&T says it plans to offer the service for a fee, but has yet to announce a start date.
