The GEAR4 UnityRemote allows TV control from an iPhone

You can buy a lot of Universal remotes that are pretty expensive, like ones form Logitech, or you could just spend a little and just put something you might already own, like an iPhone.

This is the purpose of the GEAR4, which is essentially a tiny cylinder with an IR transmitter to be configured to a TV, game system, DVD, Blu-Ray player or something else. A simple App is all it takes to wirelessly connect for a new home theater experience.

The UnityRemote is available now for about $99.
