Apple introduced there Find My Friends app alongside iOS 5 late last year. The app acts a social network, allowing users to share their current locations with friends and family.
It also enables you to literally locate your friends on a digital map. But what some of you may not have known, is that iPhone 4S owners can get a help from Siri to use this app as well.
If you already have the Find My Friends app, load it up and make sure that you are logged in. If you don’t already have it, you can download it from the AppStore for free here
Once you’re logged in, you can exit the application and call up Siri. The command for locating a person is “Find Patty Mayonnaise.” Obviously you would substitute the name of the person you are looking for. “Where is Patty Mayonnaise?” is also an acceptable command. If Siri can’t locate the person, it’s because you either haven’t added them to your Find My Friends account or they’re not currently sharing their location.
