Rogers has issued carrier update 4.1 on iTunes enabling MMS and tethering. I tried MMS and it works! When I tried tethering I got a message to contact Rogers to enable it. Rogers posted on their website that accounts with 1 GB + data plans will be able to enable internet tethering via Bluetooth or USB. I don't think they will be charging extra for MMS, since I tried it, it worked, and I didn't get any messages regarding cost.
