It looks like they are asking for testers, but I cannot seem to figure out how to add it. Do you have knowledge on how to do that (or a good place to point to to try it)?

It also looks like it is for downloading MMS only, it doesn't look like it has support (yet) for sending them.

Sorry, that looks to be a typo by me, I meant to say it works just fine for me.
