When Apple released its new iOS 5 operating system to go with its iPhone 4S, it touted¹ a new app called "Find My Friends" as a great way to track and meet up with friends. If they agree, you can see their locations on a map on your screen.

苹果公司近日最新推出iPhone4S与操作系统iOS 5，并重磅推出新应用程序“找朋友”。安装上这款应用，你就可以便捷地和朋友“偶遇”了。如果对方同意，你还可以在手机屏幕上看到他们在地图上的详细位置。

But the app's enterprising customers are apparently² already finding other uses. If the online posts appearing on a chat forum³ at MacRumors.com are for real, "Find My Friends" may have already claimed its first marriage.

Saturday night on MacRumors, a man saying he lived in New York City posted this:

"Divorcing wife. Thanks iPhone 4s and Find My Friends.

"I got my wife a new 4s and loaded up find my friends without her knowing. She told me she was at her friends house in the east village. I've had suspicions about her meeting this guy who live uptown（住宅区） . Lo and behold⁴（你瞧） , Find my Friends has her right there.

"I just texted her asking where she was and she said she was on 10th Street!! Thank you Apple, thank you App Store, thank you all. These beautiful treasure trove⁵（被发现的东西） of screenshots going to play well when I meet her ... at the lawyer's office in a few weeks.

"thankfully, she's the rich one."

"Find My Friends" uses the iPhone or iPad's built-in Global Positioning System to see your friends' locations on a map on the screen of your device. GPS can be accurate to within a few feet for civilian⁶ uses.

Apple says "The Find My Friends app is a great way to share your location with people who are important to you" -- whether you're trying to meet friends at a crowded concert or make sure your kids get safely home from school.

The new iPhone 4S and operating system have been off-the-charts successes for Apple, which said this morning that it sold more than four million iPhone 4S in three days, and that 25 million people are now using iOS 5.

Ben Crompton, who writes the Pocket Lint⁷ blog, said there have certainly been other apps before, such as Google Latitude⁸, that let you track people through GPS signals, but Apple will make it trendy.

"The burning issue seems to be that it is a very powerful tool to have," he wrote, "bringing with it huge amounts of info to the user as well as delivering plenty of info about the user to others. For some this power will outdo（超过） the user's knowledge of how to use it properly."
