Phone rang while jogging and car key fell out of pocket when I answered. Luckily runkeeper iPhone app had marked the gps location. Key found!
And in case you need a little more info than a 140-char Tweet can provide...
The RunKeeper app has a feature where you can pause and resume your run. When you do that, you get a little gray pin that shows exactly where things were paused. Another one shows where they picked up again. Since the phone application has the ultimate priority on an iPhone, the app was automatically paused when the phone rang, pin-pointing my position. So, since I don't think the developers' intent was to keep track of exact positions of incoming phone calls, it was also an example of an unintended software feature.Yours in enjoying all the GPS stories with happy endings,
