NOKIA:
No, the code wouldnt work no matter what O/s you run or how many times you try it!

And since it does not work you need not worry about stopping other people trying it.
Considering that you did not try the code every operating system you have no right to say that it will not work on any of them. I ran the script on my computer and it worked. I wouldn't recomend giving out advice like that again unless your absolutely sure its true.
