this "bug" is known since the very beginning of PalmOS v1.x. IIRC the
SDK even mentioned that it is the task of the author of any Palm OS
software to check and honor the "private"/"hidden" flag on it's own. 

While it's sad that Palm Inc did not fix this, I'm actually surprised
that this fact is new to anyone who spend any time checking the security
of PalmOS.

BTW: it's trivialy possible to remove the password and even retrive it
     in clear text with a small 3rd part application.
     Search the mailing list on ultraviolette.org (iirc, and if it still
     exists) for the program to get your password. It was posted there
     years ago.
