Google has updated its Drive cloud storage app on iOS with a handy new feature for those switching to a new phone this holiday season. It now lets you back up your contacts, calendar and camera roll so you’ll have them all available when you sign into your account on a new Android device. To use it, launch Drive on your iOS device, select ‘Backup’ in the settings menu and then select the items you want to back up. It can take a while, depending on how many contacts, photos, videos and calendar events you have stored on your device. That’s a whole lot easier...
