The extent to which your iPhone gets its fingers into the rest of your digital life increases today, as software is released that turns the touchscreen cellphone into a remote trackpad for your PC.  Touchpad for iPhone is the work of coder JS, and uses the basic framework of VNsea to allow full single/double clicking, dragging & dropping, vertical scrolling and more, all on the iPhone.  JS suggests the software as an accessory for giving presentations or controlling media, and I can certainly see how this might be handy if you use your system as an HTPC.

This app reminds me of one I used to use back in the days when I regularly had my iPaq 4150 Pocket PC to hand; PPC Tablet did basically the same thing as Touchpad for iPhone, letting you use the touchscreen on the PDA to control what was happening on the PC.

You can install Touchpad for iPhone by following JS’ instructions; you’ll need to have Jailbroken your handset, and I’m assuming this also works on the iPod Touch:

1. Start Installer.app, and go to Sources. Click “Edit”, and then Add this repository: http://cnp.qlnk.net/
2. After the refresh, install Touchpad from the Utilities category.
3. You’ll need to have VNC installed on your desktop.
