He already said MMS doesn't work for him. (Sounds like he's got no free MMS on his plan.)

I still don't get what's wrong with email (does something like GMail even still impose a filesize limitation? One that actually makes a difference for photo sharing?). If your friends have internet connectivity too you can use woof, though unless you get IPv6 IP addresses courtesy of your provider, they won't be able to connect to you when you're on 3G.
