Have a third-gen Apple TV and an iDevice running iOS 7? If you've yet to set up Cupertino's set-top box, you can do so now by simply touching your iPhone or iPad to the Apple TV. Okay, Apple's take on Bump requires a few more steps than that; you'll first need to enable Bluetooth on your iOS 7 device, then connect to the WiFi network you'll use with the Apple TV. (Your machine also needs Apple TV software 6.0 or later.) Still, it sure beats the labor-intensive process of selecting letters on-screen with the included remote. Once you've tapped your iPhone to the set-top box, prompts should appear on both the phone and the TV screen, and you're good to go. Give it a whirl for yourself -- Apple's directions are available via the first source link below.
