Apple

A few little points I'm looking into before I decide to switch to iPhone and one of those is a back gesture. My current phone is set to swipe from the right side of the screen to go back. What are the options on the iPhone without having to reach all the way to the top of the screen where there's usually a back button on the page. I don't mean changing apps. I mean going to a previous page. Is there a swipe gesture available?
