The minute our iPhone calendars turned from August 31 to September 1, TiPb’s email box started getting many colorful variations of “Summer is over, where’s our [redacted redacted redacted... redacted!] MMS and tethering!

While Apple showed off the front-end for MMS and tethering back in March, released it along with iPhone 3.0 in June, and most of the rest of the world has been enjoying it ever since, AT&T is a notable, and increasingly infuriating exception. Late summer (and when is that exactly?), and that it will be no extra charge, is all they’ve said. And whether you personally would use MMS or not, right now you don’t even have that choice.

We’ve heard all the excuses, from AT&T’s network can barely handle the iPhone as-is, and MMS and especially tethering would bring it, crashing and burning, to its knees, to a rumor that AT&T had to manually turn on MMS for every single iPhone account on their system. We’ve also heard it may be announced as part of Apple’s September 9th event. That would be very late summer indeed.

But that’s all we’ve heard. There’s been no status update from AT&T that we can find, no attempt to keep their users in the loop, no expression of sympathy for the frustration their users are voicing (or emailing us!). AT&T is being almost Apple-esque in their lack of communications and for a company that’s in the communications business — and is charging high monthly rates to its consumers — that’s just not good enough.

Is it?

Apple and AT&T are being sued in Louisiana over the lack of MMS available for iPhone 3G and iPhone 3GS users running iPhone 3.0 software. Now, it’s gotten to the point where TiPb doesn’t pay too much attention to Apple lawsuits anymore just because they’re so frequent we’d need to get the blog roomier pants, and while we’re not lawyers and can’t comment as to the merits of this case, it’s yet another (painful) reminder that AT&T has dropped the ball when it comes to MMS on the iPhone and especially when it comes to communicating what’s happening — and keeping updated — their long suffering user base.

Says TG Daily:

Apple, says the filings, has revealed that AT&T has never upgraded its towers so as to support MMS functionality. “The only excuse offered by AT&T and Apple is a mouseprint disclaimer on the website, in barely readable font, which reads ‘MMS Support from AT&T coming in late summer’”.

That’s the part where it kind of falls down for us, however. Now, I’m not on AT&T, but several of our readers are and as part of beta tests and carrier tests, some of them have indeed sent MMS messages on AT&T, and AT&T’s website seems to show it working for other phones, so… huh?

Is this once again an absurd claim distracting from the real issue — that summer grows later and later, and there’s still no word on iPhone MMS from AT&T? What are they waiting for, a Special Music Event?!
