Ok, so I don't know if this has been posted here before or if a company actually is working on this right now, but here's my idea. Well developers can now write code to interface with their own custom accessories, right? Well a great accessory would be an infrared transmitter. And the app could have transmit codes for all sorts of TVs, DVD players, Home stereos, etc, and allow the iPhone to act as a remote for... everything! If only I had the ability to mass produce that kind of accessory lol.
