One of the products I reviewed earlier this month in ' Essential free productivity apps for Android tablets' Is Lookout Mobile Security, which lets you locate a lost Android device. Last September's post on locking and finding Android and Windows phone described the remote-find feature built into Windows phones, which is tied to your Windows Live account. My post from August 2011 titled ' Keep your iPad data safe' covered the free Find My Phone app for iPhones and iPads. If you haven't already, make sure you install a find-my-device app for your phone or tablet.
