Facebook app on iphone/contacts?

[MAGnificant]

so i use facebook on my moms iphone sometimes. sorry, my keyboards being funky so i can't capitalize my letters. but anyways, i accidentally downloaded the new version where it made all my facebook contacts into her phone contacts, so all my friends numbers are in her phone. we both hate it. is there anyway to undo this

Go to the Facebook app and unsync all the contacts, Remove all the history ..
