Today, Google updated its Gmail app on Apple's mobile platform, bringing with it some features bound to be very useful for users. The iOS application is finally capable of fetching mail in the background, so new stuff can hit your inbox at any given time -- not just when you open the app. For the background app refresh to work as intended, however, the company points out that notifications will need to be turned on. Google's also made its sign-in process more streamlined, meaning that once you log into the Gmail app, you'll automatically be signed in to other iOS apps from the search giant. Because, c'mon, Google wants you to be doing Google things all the time.
