Actually, if you have a dumbphone on verizon and send more than 160 characters to another verizon subscriber, it will send and show on the recipient's phone as one long message - it calls it an "EMS Message"

I'm not sure if this is phone-side or if this just means that VZW allows 160+ chars from vzw-vzw.

Just my 2 cents and my first post after coming out of lurk-mode here.
