Re-enable Facebook's iPad app. Facebook recently accidentally released their iPad app,
but after TechCrunch posted about it, they quickly moved to disable access to Facebook from it. FaceForward removes that restriction, allowing you to use Facebook for iPad right now.
To use FaceForward, download the official Facebook for iPhone application from the App Store and install FaceForward from Cydia. You will now be able to access Facebook for iPad. That easy. I'd suggest against updating the Facebook app until they release the official version of Facebook for iPad, since it's unlikely that FaceFoward will continue to work on future versions.
You will need a jailbroken iPad to use FaceForward. To check if your iPad can be jailbroken and to see how to do it, check out jailbrea.kr. You might need to delete and re-install your Facebook app if it crashes on startup.
