Aaron Troyer knows what it's like to have his iPhone and other personal items stolen.
"This has happened probably six or eight times over the last year," he said.
Fed up, he installed MobileMe. It is an app, that among other things, allows for the tracking of a stolen iPhone.
Soon after, Troyer's phone was stolen again.
"So I thought maybe I can find my phone," Troyer said. "The phone was on, it was active and it was great."
He went to his computer, tracked the phone down to a house in Florida and called the police. They responded and once there, dialed the number and heard the phone ring. They got the phone and made an arrest.
Catch a thief, as Apple says, there's an app for that.
7 On Your Side called Apple to see if any thieves have been caught around the Bay Area, but they have yet to call back.
