A few things to note about Facebook Places:
- It works with iPhone (Facebook plans releases of Android and Blackberry versions) or use the Facebook Touch mobile site
- Configure your privacy settings!
By default, Places I check in to is set so Friends Only can see it. To change the setting click on Account,then Privacy settings and Customize Settings.Another default setting on the “Customize settings” page is “Include me in ‘People Here Now’ after I check in.” When you check in, your location is visible to your friends and also to anyone else nearby. If you’d rather be more private, you’ll have to opt out of this setting.
Your friends can, by default, check you in without your explicit approval or permission. Again, go to your privacy settings to change this if you prefer.
