Someone I know had their Android phone stolen today. It's with T Mobil if that matters. She didn't have insurance either. Anyway, they couldn't locate it with the GPS. She could apparently tell that the SIMM card had been removed. Getting the phone back seems very unlikely, but what can she do to make it useless to whoever has it? T Mobil gave her some web sites to try to track the GPS and that didn't work. She'd just like to make life miserable for the thief at this point.
