iPhone how to disable subject line in texts

am I going nuts or is this subject line in the text message screen new? It has tripped me up a couple of times because you can send text with no subject but if you happen to tap in the subject area and start typing the text will not send if there is nothing in the body area.

Is this new? why is it there? how can it be disabled?

3gs, iPhone OS 3.0.1

This is new when MMS was added.

Go to Settings > Messages > Show Subject Field > Off.

Also, just FYI...When you send a text message with the subject line it will be transmitted as an MMS. This may not matter to some, but if you don't have an unlimited plan or the recipient does not have an unlimited plan, then an MMS could cost $0.30 or more.
At least this is what happened to me when I forwarded my girlfriend a text message and put something in the subject line before sending it.
