Figured I would post this here after giving it a try for a little while. Stumbled into it yesterday when trying to find the stock android MMS application. This will indeed work perfectly on Android Kitkat 4.4.4, I do not know of other versions it will work on so install at your own risk if it is lower then Kitkat 4.4.4.
