IOGEAR has released the Composite AV Cable with Charge and Sync, a very useful all in one cable solution for iPod and iPhone owners. The name may be a mouthful, but this product has more functionality than a Swiss Army Knife.
This cable uses the 30 pin dock connector on an iPod or iPhone to connect the device to a TV, home theater, or stereo system via composite video and analog audio ports. A USB connection is included for PC connectivity, and IOGEAR even includes a USB power adapter to charge your device from a wall so you don't run out of battery while sending media to your TV or stereo. The IOGEAR Composite AV Cable with Charge and Sync can be had for around $40 USD online.
