I have a question. Really, wondering if anyone has this and has tried it for their iPhone. It says on their website "iPhone: PocketDock Line Out USB can currently be only used to sync & charge the iPhone via USB. Line Out audio is not yet available." However, since you can use a regular dock to play music on the iPhone... why not this? I know that the iPhone gives you a prompt when you dock it on a non-iPhone dock.. but still it works and plays music.
