What's with these so-called "friends" deliberately borking phones and watches? Perhaps some folks here need to reevaluate these "friends".
And what's with these tech sites reporting on the issue, including the EXACT TEXT needed to initiate the problem, instead of simply keeping it quiet until Apple fixes it. Now everyone knows about the issue, giving tools to the nimrods of the world to show how cool they are.
And just why did your "friend" do this? Was it supposed to be funny? Is he still your "friend"?
Please don't act like you have never been pranked, or trolled by a friend. Best friends do that, colleagues don't.
