But as a new iPhone owner, I have an idea. Perhaps you can set up your database with the iPhones persistent ID (Get ( PersistentID) ). Then you can set up an account and password in FileOptions so that the file opens with extremely limited privileges but then uses ReLogIn with the result of Get (PersistentID) to open the file when the user is opening the file on an iPhone. A relogin with no account name and password specified can be popped up for other users.
