Showcasing on Youtube is that Team MAC made a CFW 6.00, here are the details from them:

Download coming soon!!!
Dude, the 6.00 Firmware has only been released recently, well I have found a way to llok at the system files and create an actual WORKING CFW on 6.00! It includes the extra colors, and the network update rename. 

My observations are;

1. Why did they not put a UMD that will requre a 5.55 update like GI Joe?
2. The Youtube account was made just this September 10, 2009
3. And there's Network Update showing which should be System Update.
