I am a new Zimbra user for my personal domains and I like it so much I'm thinking pushing my company to the network edition (~50 employees, using and not liking Scalix) however I am an established Funambol user for my phones. i have the IMAP connector working with Zimbra however in talking with Funambol they said a Zimbra connector is in the works. I was thinking of using the Web Services Connector to build my own as time permits but since I found indications of a Zimbra connector from almost a year ago I hope it's near release.
I want to offer some beta testing since I have Funambol and Zimbra stood up and running. I'm excited to try it since it will bring together all of my devices and desktops, please reply or email if this is a possibility.
