There's always a chance of messing up the phone when you start modifying the factory settings. The more that I look at that video, the less I like the instructions. It looks like he's downloading software from someplace which I wouldn't do. I did some searches on a Windows Phone forum and the instructions that I've seen look similar but a little different.
