Way back when I got my iPhone, I played a bit with Orb to stream music from a Windows PC to my handset. It worked pretty well for audio streaming and was easy to access although limited to the Safari web browser. There’s now a semi-official Orb application for the iPhone and iPod Touch, but of course you’ll need to have your device “jailbroken” to use it. The Register found the above YouTube video showing how to install the application, but the more exciting stuff happens a few minutes in: there’s a live demo of remotely accessing the television guide on a PC running Orb and choosing to watch an NBA game on TNT. The television content stream looks great, especially when the device is rotated into landscape mode.I suspect we’ll see an official Orb client, not to mention one from Sling Media, once the Apple iPhone SDK comes out of beta. For now, you jailbreakers can make do with this.
