You can now turn your iPhone into a a Blu-ray remote with the new Pocket Blu app. With Pocket Blu you can control your Blu-ray movies on PS3 and any other internet-enabled Blu-ray player.
The app uses your home network, rather than Bluetooth, to connect to your Blu-ray player, allowing a much more universal remote. The application is also available for Blackberry and Android devices, and best of all, it's free.
So next time you forget to pick up the controller when you sit down for a movie, don't bother getting up again, just use your phone!
