Flash to MetroPCS already posible on iPhone 4?

I have been trying all week to find out how, but I couldnt find the way through. Ive seen people in youtube apparently using it with Metro PCS.
I have unlocked a ton of iPhones but this is my first attempt to flash the CDMA iPhone 4 to metro.
Anyone has done it successfully ??

The YouTube video is a fake. It's not that it's impossible for this to work, other CDMA phones have been 'unlocked' to work on PCS carriers, however, no one has successfully done this with a CDMA iPhone 4 yet. There are a lot of people posting on the internet with guides that do not work, and a lot of fake videos that have been altered to make people believe this is possible -- but as of yet, there have been zero legitimate posts or legitimate ways to accomplish this.

Again, it's not impossible, and it's something that may very well be coming in the pipeline -- but as of this moment, everything posted about it is a bunch of bull.
