AT&T announces that MSS is coming to iPhone 3G and iPhone 3GS on September 25th, 2009.
Previously AT&T stated that MMS for iPhone 3G and iPhone 3GS is coming “late summer” as in as late as September 21st in Northern Hemisphere.
It’s better late than never having it at all. Other Carriers outside the United States have been offering MMS since the launch of iPhone 3GS.
