I came across this site: http://www.palm119.net/. Appears to be legitimate (no warez etc.) Chinese website (my guess).

There are some nify utilities there. TreoGate caught my eye, though unfortunately, it is in a language that I do not understand. There is also something called "CallShow" and "SIMlock"
