yea I was trying to update my facebook app in the market, but it wouldn't update. so I thought it was my custom rom. I backed up the apk in titanium backup and uninstalled it (i know i'm an idiot). I then went back to market, but facebook still won't install. and titanium didn't backup facebook.apk properly. Now I don't have a facebook app.. any help would be appreciated, such as giving me the file.
