Facebook for iPhone – “Places” hangs on “Locating you…”

I decided to see how “Places” stacked up with Foursquare. I reactivated my Facebook account and reinstalled the iPhone app. Went to “Places” and clicked “Check In,” and… nothing. It mentioned something about turning on Location Services. I know I already have that enabled because other apps are using it without problem. Turns out you need to enable Location Services explicitly:

First, go to the Settings app and select General:

Settings -> General
Settings -> General

Select Location Services:

Location Services
Location Services

Make sure Facebook is enabled (On) if you want to use Places. If you want to disable Places, make sure this is set to Off.

Turn Facebook "On"
Make sure Facebook is 'On' to use Facebook Places.
