I have recently bought Griffin PowerDock 2 Charging Base for my iphone. I think it will be good for you. But my problem is I am looking for universal dock. Does anyone know about any such dock available?? Because up to my knowledge it has not released yet.

I think you can find one online for about £2-3

What iPhone 3G accessories come with a dock adapter? I just got a new speaker setup that has a universal dock setup type deal. However it didn't come with adapters. Is there any accessory I can buy that comes with the universal dock adapter for the iPhone 3G?
