That is correct, most people I know still have crappy phones that can't get e-mail, but they all get MMS, and sending pictures out to peoples numbers at their provider's e-mail doesn't always work.
Since March we've all thought that the viewmymessage torture would finally come to an end this June when 3.0 came out, only to be teased and find out we have to wait another 3+ months, AT&T has known about this longer than we have, yet they've sat on their thumbs until this week? This isn't 1899, they shouldbe able to have this done by the 17th at the latest!
Add to the fact that we're paying for MMS and not getting it, 20 bucks a month for unlimited text messaging, think about that, that's almost what we pay for data, and text messages probably use up a tenth of a percent of bandwidth that data does. So they need to get off their asses and make it happen instead of coming up with excuses.
