iPhone Adding IM and Picture Messaging?

Blogger (and early iPhone adopter) Jordan Golson just got this text message on his iPhone this morning:

AT&T FREE Msg: Good News, your messaging package now includes text, picture & instant messages all for the same price of $19.99 per month. No action required

Could this mean we can finally send pictures via MMS (multimedia message service) and get IM? The thing is, none of your intrepid GizEditors got a message like this. Sounds like a hiccup and a dream. Readers? [MacApper]
