Congratulation to AT&T iPhone user in U.S. Finally, AT&T announced that the long-awaited multimedia messaging feature will come to iPhone on September 25. Starting from that magic day, in additional to email, you can use MMS to send photos to your friends. The service will be available to both iPhone 3G and 3GS customers. For those using the 1st generation of iPhone, you’ll not be able to enjoy the service (probably you need to consider an upgrade). AT&T has explained the reason for the delay in rolling out the feature:

” We know many of our iPhone customers are eager for an update on our rollout schedule for Multimedia Messaging Service (MMS). We’ve been working for the past several months to prepare our systems and network to ensure the best possible experience with MMS when it launches – and that launch date is: September 25 for iPhone 3G and 3GS customers. MMS will be enabled through a software update on that day.We know that iPhone users will embrace MMS. The unique capabilities and high usage of the iPhone’s multimedia capabilities required us to work on our network MMS architecture to carry the expected record volumes of MMS traffic and ensure an excellent experience from Day One. We appreciate your patience as we work toward that end. “

On September 25, remember to connect your iPhone to your computer and download a carrier update via iTunes before you send out your 1st multimedia message. The update procedures should be very straightforward. Just plugin your iPhone and launch iTunes. You should be prompted with the carrier update (if it’s available).
