LG Optimus 7 windows phone still works after car ran over it (http://www.youtube.com/watch?v=ucjROnx6gY8#)
An LG Optimus 7 Prime WP7 device has been through the wars as can be seen above in the video. This particular handset was ran over by a car and while it may look shattered, it's still responsive and works as normal. The only downside is that you can't see the screen as well as you could.
The morale of the story is (apart from don't have your phone ran over by a vehicle) to purchase an LG device should you work in construction or any other practical careers.
