We have the following
GW 6.5 on a NW 5.1 machine
Win 2003 serving up Webaccess on the DMZ

I need to provide my users with a way to access their GW from mobile
phone. We do have a few Samsung sch-i730 phones.

What we want our users to access is their mail, calendars and have notify
popup when they get a new message. I was set on Omni mobile until I found
that they don't support NW 5.1.
