So it has been found within the Facebook for iPhone update. I found many guides online for how to enable it with macs but none for pc so here's how I did it.
connect your iPad to your computer
install the iPhone version of the Facebook app on your iPad
Open or download and open iFunbox ; your connected iPad should be listed there
inside iFunbox open the Facebook folder under "Apps"
navigate to the subfolder called "Facebook.app" and open it
copy the file "info.plist" to your desktop and open it (I simply copied the file to desktop then opened it with notepad)
Then change the value of "UIDeviceFamily" to "2" (from 1) it's near the bottom .
copy "info.plist" back to your iPad via iFunbox (replace the old version)
Exit device safely then respring your iPad and hey presto. Facebook for iPad opens when. Click the Facebook app.
