In many ways, the Apple iPhone is similar to the iPod including the need to be charged and sync via USB and electrical outlet. The iPhone ships with a charging/sync cable that is similar in appearance to cable that accompanies many of the newer iPods. Unlike most iPod connectors, the iPhone's connector cable does not include tension clips. However, there is no other physical difference between the iPhone and iPod's sync/charging connectors. Both can be used interchangeably.
