How do I check in with Facebook mobile?

-step by step please. I can't figure it out.Just go to http://m.facebook.com & you should see a Check In link right under the status area. Just click that & the rest should be obvious.

Another option, download the Facebook app for your phone (assuming there is one) & use that.If you have Facebook app on your phone you can use that. Go to your phone app shop on your phone. Do a search for Facebook, and it will show you the free facebook app. Download it. Sign in. Voila.
