I see what you're saying - a bit chicken-and-egg!

This piece of Palm s/w doesn't support PINs anyway. With the phone being a separate device that's only connected when you need to use it, the security issue doesn't really arise, or rather is presumed to be dealt with by the phone itself (e.g. if you can't access the phone you can't run the modem s/w in the first place).
