LOST PHONE

WTF?

Uh... How do you expect US to cut it off?? First of all we'd need to know who you are. Scary.

Then actually have remote control over any phone, or at least your carrier. Also scary.

I'd be more worried than random people on the internet can find your phone and kill it than the lost phone itself.

Talk to your carrier; they may actually be able to do something.

Don't even worry about it, bro. Just did it for ya. The phone's disabled.
