Actually, does this Samsung Dive really works?...
Let's say my phone is stolen.
1) The guy switched off the phone. Take out the sim card.
2) Go home, sit down in front of his computer. Switch the PC on.
3) Go to get a cup of coffee.
4) Switch phone on without data enabled, off GPS. Plug in to USB port to copy all your important data and photos into his PC.
5) Then use 3 button combo to go into Download mode.
6) Flash a new Stock ROM. Factory reset and wipe data.
7) Put in new Sim card and use the phone. Log in with new Google account.
Now, will Samsung Dive still be able to detect this phone....I doubt so, right?

think it is more useful to detect missing phones rather than stolen ones.
