Possible unlock?

So I came across this article that links to a website to unlock the phone. In the article he states that it's possible to unlock the G4 and its done on the back end of the T-Mobile servers and you can use the built in app after 12-24 hours....has anyone tried this website?
Here's the article http://androidandme.com/thread/you-c...g-g4-and-more/

Its links to this website http://www.androidsimunlock.com/whol...one-unlocking/

I was thinking of trying it out...but wanted to see if anyone else has used it.
