Use Your iPhone as a Mouse
For iPhone users, Logitech offers a handy free app called TouchMouse that turns your iPhone into a wireless mouse by way of your Wi-Fi network. This could be great if you wanted to sit back on the couch and control a laptop hooked up to a TV, for instance. All you need is the iPhone app and the desktop software for Windows or Mac.
Tip: If you find TouchMouse difficult to control, adjust the ‘Scrolling Speed' option under Settings on the iPhone app.

This free application for Android, iPhone, and BlackBerry devices lets you schedule an interruption or create a phony phone call on the fly.

Control a Jailbroken iPhone With a PC or Mac
Veency allows you to view and control a jailbroken iPhone via a Mac or PC using a Wi-Fi connection. The tool is an interesting application to try out if you want to control your iPhone's iTunes interface while it's connected to a set of speakers across the room, for example. Or how about typing notes into your device through the Notes app from a full keyboard? Not bad at all.
iPhoneHacks.com has a nice tutorial on how to install the software and run it for both Macs and PCs. You can find a number of VNC clients, such as TightVNC and UltraVNC for PCs and Chicken of the VNC for Macs.
Get a Personal Trainer
The huge range of smartphone fitness apps has made it easier than ever to track your exercise habits. I use RunKeeper on my iPhone to track my weekly jogs, including my speed, distance, and routes; I can even share my workouts via Facebook or Twitter. I also use Lose It to track my daily calorie intake, and for fun I use the GymFu apps to guide my push-ups, crunches, and pull-ups. Check out your smartphone's app catalog to see what's available for your device.
