One of the cooler iPhone apps to launch last year was SGN’s iFun, which let you use your iPhone or iPod touch to control games on your computer screen. But iFun only works with SGN’s own games like iGolf. A new startup, iMo, launching today at TechCrunch50, expands the ability to all PC games.

Most PC games are still played using the mouse+keyboard combination. A lot of hardcore gamers like this experience, but more casual users prefer controllers like you find on consoles. The most popular of those out there right now is the Nintendo Wii, undoubtedly thanks to its motion-based control system. With iMo, you can bring a similar experience to all PC games thanks to the iPhone and iPod touch’s accelerometer.

Another nice thing about using the iPhone or iPod touch as your controller is that it’s much more portable than traditional PC controller hardware. If you want to play a game on your laptop on the go, for example, but don’t want to lug around a joystick, you could simply use iMo, which is on a device you’re probably already carrying around.
