take on using the iPhone as a universal remote requires no iPhone adapters. Instead, a free Peel iOS app communicates with a wireless transmitter plugged into your home's router. When you use the app to turn on your TV, home theater component, or select a show to watch, the selection is bounced to the wireless adapter and back to a little battery-powered pear-shaped IR blaster, which can be placed anywhere in your living room. It sounds a little complex to wrap your head around, but the system is fairly ingenious, and the end result is zero adapters for your iPhone. You walk in the door, launch the app, and that's your remote.
