== Wired Connectivity ==

Given the wide array of wireless options it is not surprising that the iPhone has little need for wired connections. In fact the iPhone only has two. One is a standard 3.5 mm headset jack for the attachment of headphones or other audio devices. The second is a proprietary, 30-pin dock connector that, by default, is used to provide a USB v2.0 connection for synching with a computer system and battery charging. In practice, however, this connection also provides audio and TV output via specialty third party cables.
