Has anyone heard any specific updates on when AT&T plans to have MMS up and running for the iPhone? I have found a few articles that suggest "mid-July" instead of the end of the summer. But no firm dates. I've also heard that many of the "workarounds" only last temporarily as AT&T pushes a sweep to disable the changes. Also... I've heard the negatives of the workarounds such as losing Visual Voicemail. Anyone heard anything??
