Whenever my sister goes on vacation she brings two phones. Not to avoid ridiculous roaming charges, but one to give to a thief (just in case). She keeps her Galaxy and any potential robber walks away with an old, half broken Nokia.
I'd rather install Cerberus, an app designed to recover your phone if it gets lost or stolen. There's plenty of impressive functions like location tracking, an alarm, audio recording, a list of recent calls, and more. And today I've unlocked the lifetime license for all new accounts opened, normally worth $3.88, now for FREE!
