I have a 3gs running 3.0 and i want to have mms enabled tomorrow. Apple said that we can update the carrier settings via iTunes once the new settings are available, can I get the update without updating my software? Or can I just download the new carrier settings from somewhere else directly to my phone? I just want to know how to get the new settings without updating my firmware, I'm jailbroken. And there is no jailbreak yet for 3GS 3.1.
