MMS on iPhone
It seems as if all the iPhone dev teams are adding everything Apple forgot, maybe that was their plan, but this time Suavphisticated from ModMyiFone has created a MMS application for the iPhone. The application is currently in heavy development with lots of bugs. This is only the first beta version released and the dev team is still in progress on it. Currently it does not work with AT&T as your iPhone data plan does not include MMS messaging. If you are on another network with an unlocked iPhone, there is currently no MMS recieving.
This application can be obtained by adding the repository http://modmyifone.com/installer.xml to your sources list, and then updating the refresh on installer.app.
