AT&T announced new 3G pricing plans Wednesday that will make iPhone and iPad bills less expensive for most customers, but will also put a stop to unlimited data plans.
Under the new pricing scheme, 3G data service for AT&T smart phones (including the iPhone) will cost $15 a month for 200 megabytes. If customers download more than 200 MB, they will be charged an additional $15 for each subsequent 200 MB that they download.
