So this kat Papa Smurf151 on xda forums is said to have inverted the colors in this Facebook app. So I thought I would share my findings.
After some research it appears that most of the images and all edited code was taken from the darkedge themes. Why do some people try to take credit for other peoples work. Its ridiculous.
[Release] DarkEdge UI
Here is the link from XDA Forums http://forum.xda-developers.com/showthread.php?t=708004
I uploaded the apk, later tonight I'll update this post with an update.zip install.
For now if you want it just change the .zip to .apk and push it to system/app on your phone.
