iPhone 4S前不久在中国正式发售了。“苹果迷”们终于可以一睹它的风采了。新的iPhone 4S推出了一套新的应用程序，你只要获得对方的同意，就可以准确的在地图上找到对方的位置。

    这个应用可给家长们带来很多方便，可以随时找到自己的孩子，是不是放学了，还是已经在路上了，又或者还是在学校。但是也有些人通过这个程序，像侦探一样，成功的找到了自己伴侣出轨的证据！看来科技对于一些人来说方便了我们的生活，对于另一些人来说，也实在有些“无可奈何”呀！下面就一起来了解一下关于iPhone 4S的这个应用系统吧。

 When Apple released its new iOS 5 operating system to go with its iPhone 4S, it touted 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.

But the app's enterprising customers are apparently already finding other uses. If the online posts appearing on a chat forum 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. Lo and behold, 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 trove 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 civilian 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.

Ben Crompton, who writes the Pocket Lint blog, said there have certainly been other apps before, such as Google Latitude, 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 the user's knowledge of how to use it properly."
