This makes sense except for the following:
1. If a cell phone is lost or stolen one can contact their service provider and have the service suspended. This can be done in minutes after having notified the cell phone provider.
2. I would imagine that in a college town like Perugia most if all students have cell phones. So who would be the market for a stolen phone?
Europe uses GSM phones. You can simply swap the SIM card and start using the phone. New SIM cards are available from any store that carries cell phones.
