MMS with n900

Is it possible to send MMS and voice dial with the phone.  I see SMS mentioned but nothing about this?

Update:

It is entirely possible and largely always has been.

fMMS is your friend.

I installed FMMS some time back but haven't got it to work yet.  I am not sure what to fill in the boxes with.  I put in what I think and try to use it and says " operation failed name of service not known, please check your settings"

In access point I have AT&T INternet, don't know what goes in MMSC or what user name do I use--do I have one on the phone or is it a new one---and do I set up a new password--just not sure if some of this is from information I have in the phone for my email and that kind of thing or if it is all new???

Thanks,
Bobby
