Phonegap builder - is there any Hybrid Facebook connect solution out there
based on JS only?

Im currently developing a simple pure CSS, HTML, JS solution - consisting
of one .html file with a couple of .js files included.
Im building / compiling this into a Android/iOS app through the very smart
Phonegap builder located at: https://build.phonegap.com
What im looking to do is to integrate Facebook connect in my application
and use it as an easy way to create a user.
I've done this before with the Facebook Javascript SDK on a website
project - however I figure if I want to keep the Facebook Connect process
within the Android/iOS app, then this would require some native coding?
Is there anything like a hybrid Facebook connect solution (?) out there
that would enable one to code using the normal Javascript SDK, and then on
native, it would have a native fallback?
It seems to me that should be possible with:?
https://github.com/phonegap-build/FacebookConnect/blob/master/README.md
However by the looks of it, this "jumps" out of the box on only dealing
with your plain simple .js files?
For the note: I have no experience with native coding -Xcode, Eclipse etc
- so trying to avoid this - but not sure if that will be possible.
Any suggestions are welcome - thanks! :)
