Transferring Data Via Dock Connector

Plug the 30-pin connector into the bottom of your iPhone, then plug the Universal Serial Bus end of the connector into any available USB port on your computer. Your computer will recognize the iPhone and open iTunes for transferring content to the device.
Transferring Data Via Wireless
You can also transfer data, ringtones, files and other content, to your iPhone via the device's wireless (Wi-Fi) or Bluetooth connection. The content transfer time varies depending on Wi-Fi speed — data plan or Bluetooth strength. This transfer process is completely wireless and completed without the use of your computer.
Your iPhone comes bundled with the 30-pin dock connector cable for transferring data as well as specific instructions on how to connect the cable. The Wi-Fi and Bluetooth technology are built into the device and don't require any additional equipment.
