I'm trying to find an external antenna connector for a 600 in Australia. I have a Yagi I want to connect, but am having trouble finding a connector. There seem to be some for the 680 though. Are the connectors for the 600 & 680 the same?

Does anyone know is the plug to go into the back of the phone just a standard FME? Anyone know a source that will post to Aust? Anyone know any other inexpensive solutions to the problem?
