How do you implement an iPhone style date picker in tileStack? I see a mockup version, but how do you get one operational with speak commands?

The silence is deafening! I guess nobody from tileStack monitors this or helps with these questions. There are lots of iPhone controls that seem missing, and I guess at present, no way to do them. Unfortunately, to use tileStack to do iPhone apps, we really DO need to implement date pickers, etc. or the apps we generate will look rather odd.
