I don't have an iphone - waiting for version 2. How does video voice mail work? I know that each message is captured on the iphone itself in the form of an MP3 or AAC or similar file. I assume this means you don't have to dial in to get messages, and theoretically you don't need a cellular signal at the time you listen? When are the messages recorded to the iphone? If you are out of range or have the phone off, do messages automatically download once there is a cell signal? Since these messages are audio files, are they downloaded via EDGE or WiFi ? If so, could you retrieve messages (or even know you HAVE any messages) if you do not have EDGE or WiFi at the moment?
