Around a year back, my brother gifted me an iPhone 3G. It was a welcome upgrade to my 2 year old iPhone which had seen better days. It was all sparkly and shiny and I was thrilled. In a moment of infinite wisdom, I plugged it in for charging around 7 feet above the ground in a precarious position. As soon as the next email alert came in, it vibrated and fell to the ground, completely trashing the screen.
Despite all attempts to get it fixed, including spending hours with technicians and a lot of money on replacement screens and whatnot, it never worked properly again. It finally croaked a few months later.
