News from AT&T says that MMS will be available on the iPhone 3G and 3GS beginning September 25th via a software update.
The date is September 25th, which does indeed fall a few days past the official end of summer. It was important to give our customers a positive experience from day one. We support more iPhone customers than any other carrier in the world so we took the time necessary to make sure our network is ready to handle what we expect will be a record volume of MMS traffic. We truly appreciate our customers' patience and hope they'll understand our desire to get it right from the start.
The service will be enabled with a software update on the launch date. Customers can obtain the update from iTunes, just like all other iPhone updates.
As for tethering, 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. We expect to offer tethering in the future. [TUAW]
