Want a free Logitech wireless trackpad and keyboard for your PC or Mac? Gizmodo says try your iPhone!

Logitech is offering a free Touch Mouse app in the iTunes store that—with the help of the companion Touch Mouse Server software from Logitech's website—will let you use your iPhone as a wireless mouse and keyboard with your computer. You can configure it as a two- or three-button mouse, and the multi-touch supports two finger scrolling. You can rotate the iPhone to either portrait or landscape modes and the wider setup makes keyboard usage easier. The keyboard includes Ctrl, Alt, and Command/Windows keys, and the text is displayed on the iPhone as you type so you don't have to keep checking the computer screen.

The connection uses WiFi rather than Bluetooth, so you're not required to be at close range to the computer. When you load the app it lists all computers on the network with the server software installed. This would seem ideal for media server applications, or if you're laying on the couch and you hooked your laptop to your TV to play Netflix or Hulu.

This is not a new idea, but Logitech's name on it gets some attention. The free price should make this a popular download, and it will probably catch on even more when the iPad is out and the larger surface is available for touch motions and keyboard usage.
