Go ahead and enter your sync settings on the Mac, do a sync of the default database to your sync location, and send the settings to your phone.

After OmniFocus for iPhone grabs the new settings, it'll start a sync, see that there's a database already there, and ask you which one you want to use. You want to choose "Local Database"; that puts the database on the phone up on the server, replacing the one that's already there.

Next, return to your Mac and do another sync. You should see the same question you got on your phone. This time, you want to choose "Server Database" - we'll copy the sync database to your Mac and you'll see the information show up.

Basically, the only thing you need to avoid doing is saying "Server Database" on the phone while you're setting things up.

That help?
