Query: If you're buying this for your iphone, don't bother.. it doesn't work

I bought this device primarily for my iphone, as the iphone is listed as one of the supported players. It was suppose to be an all in one device, i.e charger and player; but, after carefully reading the enclosed directions, I couldn't even get the device to charge or play the iphone. It may work on an mp3 player, but I'm not taking my chances.
