Following up on today's announcement that AT&T would be making MMS available to US iPhone users on September 25, TiPb asked the logical followup -- tethering?

We expect to offer tethering in the future. By its nature, this function could exponentially increase traffic on the network, and we need to ensure that some of our current upgrades are in place before we can deliver the expanded functionality with the excellent performance that customers expect.

They're likely referring, at least in part, to their ongoing rollout of 850 MHz 3G -- most recently in New York and New Jersey -- which should put more width in their bandwidth.

So are we happy enough with MMS to cut AT&T some slack on tethering, or do we want it all and now?
