Juice Wireless, Inc, has just released Flutter (iTunes AppStore Link), an AppStore app which (kinda) allows you to send MMS from your iPhone.

The app is definitely still in a beta format, with a bunch of supposed limitations (can only send to folks in your contact book - can't just tap in a number, can't receive MMS, location support is buggy - far off usually, and not everyone seems to be receiving the MMS's), but its up.

However, either the app is a joke, or their servers are much more overloaded than they thought would happen - I have yet to even get the confirmation sms, much less be able to test the app, and its been hours. I will update this post with a more involved review when (if?) it comes through.
