i have a question about this new Universal Dock. could i use it to connect to my TV and just play music that way? i have a 4g ipod and would love to be able to transfer by TV into a stereo that way, as it has great sound. i think you nee the new apple AV cable to plug it into the TV with. it won't work with the nano. does that mean it won't work at all or just for pictures?
