If you carry around an expensive smart phone, it’s a good idea to have some sort of security program installed to protect and track it in case of loss or theft.
If you have an iPhone or iPad, you may want to sign-up for a MobileMe account so you can utilize the Find My iPhone application. There’s an annual fee, but well worth the money if you lose your phone. Check it out »
If you have an Android, Blackberry or Windows Mobile phone, check out Lookout or Prey. Lookout scans your phone for viruses, backs up your data and will track your device if it is lost or stolen. Prey tracks your device if it’s stolen and allows you to lock out unauthorized access. It also can be set up to track your personal computer. Both are free services with options to pay for additional features.
