A number of other wireless carriers throughout the world will be supporting MMS at launch.
- Internet Tethering: At its previous media event, Apple chose not to focus on tethering, addressing it only in a Q&A period by saying that while the functionality is being built into the iPhone OS 3.0, cooperation from carriers would be needed in order to enable it. During today's keynote, Apple announced that tethering via USB and Bluetooth will be offered on a number of carriers at launch, although AT&T will not be supporting it for the time being.
