AT&T: No extra cost for iPhone MMS messaging

AT&T will not charge iPhone users with text messaging plans anything extra for MMS messages, according to a FAQ list (PDF Link) posted online. Support for MMS messaging will be included in iPhone OS 3.0, which is launching this Wednesday, June 17. Unfortunately, AT&T will not have its network ready to provide MMS service to iPhone users on that date, and has only said that the feature would be activated “later this summer.” In addition, the company has also committed to providing tethering support for the iPhone 3G and iPhone 3GS, although it will only say the feature is coming “in the future.”
