Nokia 6820 / 6820i

Does anybody have any good experience connecting Ipaq1945 to N6820? I am really having hard time with this. I called Nokia they told me the problem is that Ipaq is using a "unit key" code to give the password to N6820, but N6820 is expecting a "Combination Key" code. I went back to HP and they gave me a patch and a rom upgrade but still does not work ... I managed to connected once (some how) but I cant repeat it?

Anybody has any experience with this?

Thanks
