AT&T Corp. is considering to launch a cheaper data plan for its popular iPhone handset, according to a report over the weekend.

Business Week based its report on information from unnamed people with knowledge of the company's thinking. AT&T may soon offer a limited data plan for the iPhone, the report said.

It said a plan could be introduced this month that would include limited data access at about $20 a month, a $10 reduction. The price cuts could be a way to attract customers from other wireless carriers if Apple remains with AT&T.

BusinessWeek speculates the lower prices are part of the negotiations to keep AT&T as the exclusive wireless carrier for the device.

A new version of iPhone software is expected from Apple at the World Wide Developer conference in June. Meanwhile, there are also rumors that it will unveil a cheaper device this summer.
