Several AT&T iPhone users have reported today receiving text messages from the wireless carrier informing them that the company's View My Message workaround for receiving multimedia messages will be deactivated as accounts are prepared for MMS activation on September 25th.
AT&T Free Msg: Picture & video messaging (MMS) will be available for iPhone on 9/25. While we prepare your account for MMS capability, the current "view my message" experience will be turned off but your ability to send and receive text messages will not be affected.
The View My Message service has been viewed by many as an inconsistent service that offers an awkward experience for users. Consequently, the addition of full MMS support from AT&T has been a highly anticipated addition for many iPhone users in the United States.
