Find my Friends, the iPhone, iPod touch and iPad application that allows you to locate family members and chums, has appeared on the App Store already - even though the operating system, iOS 5, it requires to run is yet to be released.

Published by Apple itself, Find my Friends is an iOS 5-only app, and uses the Apple ID you create with iCloud (when that's possible). Your contacts will also need to install the app and sign in, and then you will be able to see where they are, anywhere in the world.

It doesn't just spy on them covertly, however. Whenever you want to see where your friends are you must send a request, and if agreeable (or available) they will then allow you to locate them on a detailed map. And anyone with the application can even set it to show their location to all contacts on a temporary basis.

For example, if you are on a 2-week holiday to Borneo, you can set the app to go live at the beginning of your trip and to switch off at the end.

You can also send a message to someone via the app too, and there are plenty of privacy and parental controls.

The application is totally free, but does require an iCloud account as well as iOS 5 on an iPhone, iPad or iPod touch. We are awaiting the launch of iOS 5 later today, and Pocket-lint will bring you updates up to (and beyond) its launch.
