You can already use your iPhone to control your iTunes on your computer using Apple's Remote app, but you've never been able to use your iPhone as your TV's remote control. But that's about to change.
A company called L5 Technology is releasing the L5 Remote next month, a $50 infrared dongle paired with a free app that turns your iPhone into the ultimate universal remote.
The app lets you drag and drop buttons around on the screen to set up just how you want it to work for your various devices.
The dongle doesn't require batteries, and it looks pretty sweet, although we'll have to see how it actually works before getting too excited.
