Tracking a stolen iPhone led to an elaborate chase through the streets of San Francisco earlier today, reports the San Francisco Chronicle. Around 6:30 AM, two armed robbers stole an iPhone from a person on a street in the neighborhood of Ocean View. Using a GPS tracking app -- possibly Find My iPhone -- police were able to narrow the phone's location down to a place in Noe Valley. When the suspects spotted police closing in, they ran, and one of them tried to climb over a gate near St. Paul's Catholic Church.
