iphone data adapter with usb and 3.5mm, where to buy?

[ug.mac]

Hi guys,

I need an adapter connect to my iphone data port while allow usb connection to charge and a 3.5mm stereo jack for audio output. I need something like this because I'm trying to solve 'cable chaos' in my car. I want to be able to connect and mount my iphone 3G by just simply connect adapter to data port, instead of audio cable to top and charging to bottom.

Anyone know if there is a such thing?

Thanks.

ug.

Thanks for the link, The idea is what I'm looking for but product is too pricy and remote just a waste for me. I actually found an adapter via Google image but it's quite confusing since title says it will work with iphone 3g but detail info is totally different.

I'm also thinking about modify the data cable myself if OEM cable is prewired and someone can post the wiring diagram. data cable just have four wires.... not an option......
