How to send as mms and not email?

Hey guys.

Can anyone tell me how to send a picture as a mms to an email address, but not as an email?

I'm trying to send a mms to mobile@facebook.com to get an authorization code so that I can start uploading pictures from my phone, but I think it's not working because it's sending it as an email. With other phones, you select mms and then you can type in a number or an email address you want to send it to, but with this phone there's an option to send it to a number OR and email address. And I have a feeling that when you select email address it sends it as an email and not an mms.

I hope this makes sense to you guys, and I hope someone can help.

Yes I know we can't activate it through the website, but I have several friends who have t-mobile and they always upload pictures directly to their pages from their phones. And they explained that although t-mobile is not a choice in the website, they said that if you send a mms to mobile@facebook.com they will reply by sending you a text with an authorization code which you can then take to the website and activate there. 

If you figure out how to do it could you let me know? I'd like to be able to send pics to FB too.

thanks
