Since it's been known that different generations of the iTouch have different accessory/cable compatibility, what is the proper iPod to TV Audio-Video Cable for the iPod Touch 4G? I'm not falling for the rip-offs on the Apple Store; they try to charge 50 dollars for something I could get for 10 with the 1, 2, and 3rd gen. However, given the newness of the Touch 4G, are there any other places I could get a sure-to-be-compatible AV Cable? Or should I risk getting one that is known to be compatible for 3G iTouches?
