Even if it was, which I seriously doubt too, I can see no serious use for it. Mobiles aren't on the internet all the time anyway. You'd have to catch the person on there while they were on the internet which at the prices won't be often. And what would you do if after the time effort and money you did actually manage to Hack them? Nothing!
Don't bother even trying.
