Although my PlayBook is Wifi only and not tied to any carrier, the AT&T Family Map app was installed with the latest beta OS update v188.8.131.520. If you aren't aware, the AT&T Family Map is a easy way to keep track of locations of your family via your device or computer. Nice for those parents out there who want to keep tabs on the kids. Have a BlackBerry PlayBook and want to download the latest Beta OS? You can get details here.
