Tired of shelling out $30 a month for data services to send and receive e-mail and surf the Web from you iPhone? If so, you may be in luck. Rumor has it AT&T, the exclusive carrier of the iPhone in the U.S., is considering offering a less expensive $20 plan.

While $30 gives you unlimited data access (5GB in actuality), the supposed $20 plan will likely cap the amount of data you can send and receive over AT&T's cellular network. A cap would certainly be welcome to those families with more than one iPhone.

With voice plans for the iPhone starting at $40 per month and no way to share data plans, it would offer users some savings. Now if only there was a pot of data, not just voice minutes, users in the same family could share.
