I have the 3G and i was wondering if I jailbreak will I now be able to send and recieve MMS messages? If so how?
The original iPhone doesn't support MMS. The 3G and 3GS both do by updating to the most recent OS. Who is your carrier?
You should have a carrier update that gets installed that enables it. It wasn't right when 3.0 came out like most of the world LOL.
