I am using Notes R5, but I believe this supports 6 also. They have wonderful responsive support and provide a 30 day evaluation copy of the sw...new license cost $75USD. Their website does not mention supporting the Smartphone 2002 OS but they do, especially on the MPx200. This sw is very easy to use.
