Around the release of iPhone OS 3.0 and the iPhone 3GS, rumors started to fly concerning MMS and tethering, both of which would get 3.0 support. The word was AT&T was unnecessarily delaying MMS, maybe as far as September, and that tethering would run AT&T customers as much as $55/month.

According to AT&T, none of this is true. They recently sent an email to Wired.com to set the record straight. A spokesman for the company has confirmed charges for tethering (booooo!) though he wasn’t willing to mention specific numbers or a live date for the service. As they’ve stated before, the email maintains MMS for “later this summer.”

By the by, the first day of autumn isn’t until September 22, giving plenty of room for “later this summer” and “September” to mean the same thing. As for tethering, we’re probably looking at a $15 upcharge, which is consistent with other tethering/data plans. Seems egregious on top of an unlimited data plan, but I don’t have much use for tethering. My apologies to those of you that do.
