Once received, time it took for police to recover it: Really fast.
Final thoughts: Surprised!
Full story below:
Around 7:00pm two guys with guns in a motorcycle, robbed my phone... As soon as I get home I actived prey in the website and nothing happened... Next day when I checked my email there were 6 Prey reports available and also the configured backup number to receive an SMS with the SIM the guys put on my phone. I went with all the data to the police (and to be fair, I wasn't really hopeful about recovering my phone, I just did hoping no one else would get robbed by these guys again). 7 days after that, I received a call from the policeman assigned to my case who told me they have my phone and I could get it back whenever I wanted. I was amazed, I never expected to recover it.
