EDIT: As of Facebook v10.0, this question received a lot more views as the option has moved again. See the new answer below.
Original Question
I'm using Facebook v6.8 on iPhone 4 running iOS 7.0.4.
In previous versions of Facebook, I could tap a cog icon in the NewsFeed box and select whether to sort by Top Stories or Most Recent. I can't find that icon any more.
How can I sort by Most Recent?
Best Answer
Whilst at the top of your feed, pull down so you see the News Feed button. Tap that and you can select from All Friends, Most Recent. Lots of other choices are available if you expand the list by tapping the downward facing arrow.
