(keitai-l) WML access to phone variables

Hi All,

Quick wap question.  Does anybody know if there is some way to access 
details about a phone from within the WML environment?
I'm sure that if there is it is likely to be massively phone 
dependent.   What I am really interested in is if you can get access to 
a users bookmarks, or to their url history.   I can see some functions 
in wmlscript that might be used in this way - there is the enigmatic 
setVar and getVar in the WMLBrowser package, and I have read the 
WMLScript specification on this, but it says no more than you can go 
setVar(name) and getVar(name)

There is also mention that WMLScript can be used to access the 
UserAgent, but I can't see a specific example like getVar("UserAgent") 
.... Does anyone know of  alist of variables that can be accessed in 
this fashion?

Many thanks in advance.
