Lookout Remotely Backs Up, Protects, and Manages Your Smartphone's Data/Windows Mobile Theft

You'll need to download a quick app to your phone, which gives Lookout access to it (as well as displays the status of your backup and anti-virus on the go). Most of your work with Lookout will be done on your computer, though, from Lookout's web interface. From any browser you have access to all of Lookout's features: you can back up your phone, find it if it's lost, wipe your data, and run virus scans remotely. It's super easy, requires very little setup, and is an invaluable safety net if and when your phone falls into the wrong hands.
