According to Rogers PR, they will support MMS and tethering with the intention of making the service availble with the June 19th launch. That means these features will not work with current pre-release installs of 3.0. Rogers would neither confirm nor deny whether MMS/tethering would require a more expensive pricing plan.

Also, Rogers will be bringing back their limited time 6GB@$30/mo plan. So if you’re finding yourself using most of your 3G data, you’ll have a chance to upgrade.
