One of the more interesting things you can do with the iPhone is use it as a remote control for other devices. Since the iPhone App Store launched almost two years ago, developers have created hundreds of remote control applications.
Some of them are for entertainment — designed to control A/V equipment in your living room. Others control household appliances, functions on your computer, or even expensive corporate security systems.
For now, most remote control apps operate over the Internet, or via a wi-fi or Bluetooth link between your iPhone and another device. But one company is developing an infrared iPhone accessory, which will open the doors for even more remote control applications.
