I once was a stubborn holdout on smartphones but now I’m a zealous convert. On a recent trip out of the country and out of my phone’s data network, I felt a little dazed and out of sorts without my constant handheld companion. I confess that I used some free, unsecured WiFi during the trip. While I was vigilant about the type of info I was sending and receiving, for all I knew, my smartphone (and passwords and bank info and all manner of personal data) could have been accessed during those brief, careful sessions. And when I read this chilling cybercrime report from Norton, I vowed to change my sloppy smartphone habits.
