No one is immune from such situations, which is probably why I always try to do everything to reduce such risks. If I got in your situation, with the police suspecting me of a crime, because of that phone that I lost recently, I would definitely show my VoIP call history from www.usechalkboard.com, because all the information is saved there and I would be able to prove my innocence. It would help a lot to prove for example that the phone was stolen, it would exonerate me most likely.
