Swiping Back

Those little arrow button are so small and out of place in Safari aren't they?  In iOS 7 they are still there, but there is a gesture to do the same thing. Swipe from the left to go back to the previous screen

The universal back gesture allows you to swipe back in Safari, Mail, Settings and any other supported app.  You'll be saving your thumb from that long stretch.  Simply swipe from the left side of the screen and you'll be taken to the previous screen.
