Facebook Places Check Ins Not Yet Available For All iPhones

So you just downloaded Facebook’s new iPhone application with excitement hoping to post your first Facebook check-in with the new Places application, but for some reason you can’t, right? Don’t be alarmed. Last night I too was confused as I was greeted with the new Places icon in the Facebook iPhone application but couldn’t figure out how on earth to check-in. Instead I’m teased by my multiple friends who are checking in around the world.
