Facebook Timeline and Facebook Apps?

Charles,
What you linked to for Best Buy wasn't an App but a Facebook Page. You can create a Facebook Page easily, but it's different than an app. An App lets you display your site within Facebook. A Page is a 'profile' page for a business or other non-person entity. You can create a page at:
www.facebook.com/pages/create.php

Hope that makes sense, but if you need more information, just let us know.

Charles,
With a Facebook Page, you can create a "Page Tab". That will show a portion of your site within the Facebook Page. You can see the example on our Facebook Page at:
www.facebook.com/sourcecoast
Once there, click the "JFBConnect Demo" box underneath the cover photo. That will then load a page from our demo site which is fully configurable from JFBConnect. To set that up you can follow the guide on the page below:
www.sourcecoast.com/jfbconnect/docs/facebook-page-canvas-setup

Hope that helps get you started, but if you're looking for some other form of integration, please let us know exactly what you want to accomplish and we'll let you know how to do it (if it's possible).

Thanks,
Alex
