8.3. Connect with Bluetooth

Want to use a wireless headset with your iPhone or send documents from your iPhone to a printer? If so, you need to know a bit about Bluetooth, a wireless technology for sending data between two devices that are a short distance apart.

Bluetooth is used in home entertainment systems and to connect wireless mice and keyboards to a computer, allowing you to do away with inconvenient or unattractive cables. It’s also responsible for the phenomenon of people wandering around in public who seem to be talking to themselves—until you notice the Bluetooth headset they have stuck in one ear.
