Great job! Was being funky at first but it was my fault -- I had 3rd party access disabled in the MIUI ROM's messenger settings. (Droid Incredible) No problems thus far, aesthetically things could be better but the functionality is there. Feature request? I think it would be awesome if you could almost imitate the "Bridge" functionality of the BB PlayBook -- E.g. send texts to a Honeycomb tablet.
I have it installed, I seem to have issues sending texts from the web interface. Reading them and the notifications are great though. I tried emailing your support email and that bounced too.
UI is a bit buggy as well, too.
Again though, the base featureset is a big win.
