Using Colonels latest, does/can sprint charge for MMS?

[Gnfghtr]

I think that I'm paying Sprint quite enough for what I use the phone for. That being said, I want to maximize what I can do, like everyone else. I have not paid much attention to the SMS or MMS features of the 6700. Every once in a while, I get a message and haven't seen a charge for it on my bill.

Can I send MMS messages without accruing an extra charge? If so, how. I haven't seen a walk thru on setting up a MMS system.

Thanks for all your help,

Dave
