I have setup GW Mobile 2.02 on a Windows 2000 SP4 computer and have it
accessible from the Internet throught HTTPS. I am able to go through
Internet Explorer on a computer outside my firewall and access the login
page as well as login into the site.

Now on my bosses Sprint Smart Phone with Windows Mobile 6 I can browse to
the login page but after that it gives me an Authentication Failed
eventhough it is the same username and password used on the Windows XP
machine outside the firewall.

Ay ideas why?

Since I still own a cheap cell phone I have no clue where to start.

Just wondering,
