Actually, you can unplug the phone while it's attempting to do the wire trick. The only reason I know is because I did it lol. The thing not to panic about is that when you turn on your phone, it won't work. You'll just have to continue the process by replugging it in and doing the whole process. It didn't work with my desktop, so I unplugged my phone and used it on my laptop, which has Windows 7 compared to Vista on the desktop, and it worked after maybe the second try.
