When version of zimbra? No mobile sync in open source edition. You need to buy network edition and purchase the mobile option.
Activesync on the phone will tell you if there is a certificate problem, and that doesn't sound like your problem. You don't need a commercial certificate to do this. I have multiple phones setup with a self-signed cert and it works fine. You just need to export you root cert, and load it on your phone. Once your root cert is exported, it's pretty easy to get it onto the phone with either a storage card or by loaded the cert file on a web server and pull it in with the phones browser before you setup the activesync.
