Marius has been working on it and has had minimal (which is better than none) success with the Symbol. The Symbol was chosen because it was a Type I form factor (so all CF users can use it) and the SDK was readily available.
I am trying to get the SDK for the Prism stuff but it doesn't look promising.
We are all waiting patiently for the day the new thread starts, "Symbol is now supported"...
