I found an iPhone app which was developed by Apple called 'Find My iPhone'. This app comes to our rescue when we lost our Apple products like the iPhone, iPad, iPod, Mac, et cetera. We can locate the lost device's on a map by accessing this app on another iOS device.
This app has several other features like locking the lost device, gives the directions to the lost device, can set an alarm even if the lost device is in silent mode, erase the data in that device. This is a must and should app installed on every iOS device. Try it out for yourself by downloading from ITunes-Find My IPhone.
