With the announcement of the new iPhone, we figure there will be some new interest in this bit of software that's been around for a while: Do you have a computer without one of those newfangled infrared spots and a remote control? Do you still want to be able to change tracks on iTunes or pause a movie from across the room? As long as you have an iPod or an iPod Touch laying around, Signal is the app for you. Its interface is almost indistinguishable from the regular iTunes player on those devices, which makes it a breeze to use. Here's how it works: download Signal and open it up, then input the IP address it gives you into your iPhone or iPod. Boom! You can access all your iTunes media from your device. Signal lets you change speakers, adjust volume, turn on shuffle or repeat, and pretty much anything else you could do from within iTunes.
There's a full demo, so you might want to try it out before you shell out 25 bones, but here are a couple of things to consider:. If you're going to buy a standard remote anyway (like the Apple Remote, for example), remember that Signal will work with your iPhone or iTouch from anywhere your network reaches, so you can use it to shoot around walls. Also consider that Signal has both Mac and Windows versions, where some other remotes only work with one platform.
