ok so i have the blacked out android market installed and everything but the facebook app and the twitter app that come with the droid updates and installs fine. but when i try and update facebook or twitter it says that they weren't signed correct. i tried downloading the APK and installing it manually but nothing happens it keeps telling me that it can't install it. is there some way around this? or is there a custom verison of the stock facebook app similar to the market?
