I'm using your application with Droid, and have noticed a couple of issues.
First, joined contacts appear as separate contact entries in the contact list. For example, I had two entries of "Mrs. Gambit" on the list; on the main contacts app (anyone have a suggestion for one with instant search and/or heirarchies and groups? aContacts just crashed a lot.) it only shows up as a single entry.
Second, notifications don't appear to match the users at all, even when the phone numbers match. The general SMS event is firing, however, so it is properly engaged - the notification at the top shows up from 'Unknown'.
Third, the 'White' LED color shows up as a lighter blue than the light blue. More of a turquoise. All of the rest of the colors look approximately correct.
Forth, custom patterns of buzzing work, but the LED doesn't appear to behave any differently regardless of the options specified. I'd love to have an 'always on' led option (two 'always on' events would split by half the time, etc).
HTH, happy to test new versions, thanks for the good work, even if it's not quite functional on this just-released-platform google's unleashed
