Having access to Wi-Fi on an iPhone allows you to minimize the impact on your data plan and, ultimately, your phone bill. Being able to use Wi-Fi for Internet access when you are near an available wireless network means you can use online services without worrying about how much data you're using up. Accessing Wi-Fi on an iPhone is straightforward, as the user interface is designed to give you control and ease of use.
To find available networks in the current area for the iPhone to connect to, choose "Settings," then "Wi-Fi" and any networks detected will be displayed. Tapping on a network will make the iPhone attempt to make a connection to it. The "Wi-Fi" icon will appear in the status bar when you are connected to a network, with the number of bars indicating the strength of your connection. The connection strength depends on the network itself and on how far you are located from it.

Tap the entry for the Bluetooth accessory when it's detected by the iPhone and displayed on the screen. If the accessory requires you to enter a passkey to complete the connection, enter the number when prompted by the iPhone.
