Subject: Have you considered Lotus Traveler?

Lotus Traveler 8.5.1 support for Mobile devices now covers:

Windows Mobile,

Symbian, and

iPhone

It’s fairly easy to set up and configure, and only requires one additional port to be opened on your Firewall if you’re already running a secure Domino web-server.

Yes,We have traveler 8.5 and we are going to upgrade to 8.5.1 but it doesn’t support all mobile phones like gmail?

When will traveler support android?
