Today I took a deep breath and sprung for the unlimited family texting plan. Our daughter (on our plan) moved away for the summer and really wanted to text her friends. So I'm sure she and my wife will be getting a lot of use out of it. 
While I was on the phone with the AT&T rep, I asked if the texting plan also included MMS. I expecting her to say it would cost extra, or that the iPhone can't do MMS. But to my surprise, she replied that currently I can't do MMS, but when the new iPhone comes out I'll be able to and it will be included with my texting plan. So that was a bit of good news. I was impressed that an AT&T rep knew about the upcoming iPhone and what it could do.
So far I've been really impressed with AT&T's customer support. Every call I've made, the reps have been extremely knowledgeable, pleasant and helpful.
