While at the dry cleaner one day, Rob's iPhone was stolen. He immediately chalked it up as gone forever, and proceeded to purchase a brand new one that same evening. It was the next day when unfamiliar contacts began to appear on the new phone. The (not-too-bright) thief was unwittingly supplying him with names and phone numbers of his or her closest friends, via the magic of MobileMe synchronization from the stolen phone to the cloud and eventually to his new phone. "It didn't take long for me to realize that MobileMe was leading me right to the thief!" wrote Rob.
Rob provided the list of contacts to the police and they recovered his phone that same evening.
