It's not the first peripheral that turns an iPhone into a universal remote control, but this Power A case means you don't have to slip it off when you've stopped using it at home - it's got two functions.
The app is free to download for both the iPhone and iPod Touch, and provides the interface for controlling any IR-equipped device in your house. The case meanwhile, has the IR transmitter and looks like a discreet offering from Griffin - not too big and bulky, in other words. It'll go for $US60 when it goes on sale soon, and as with all iPhone apps, there's the very real possibility of OTA updates to add more functions. [Power A via SlashGear via Geeky-Gadgets]
