I know with my iPhone I can go to a website and see where my phone is at all times within a few feet, and lock it or perma wipe it (can restore off my backups). I imagine you can't do this. I'm assuming yu have reported the phone stolen to the police, at this point I'd have it turned off and either buy another or claim it on insurance and get another. I'm sorry to here taut btw, I would die without my phone.
