Actually it's known as Manila 2.1, Rhodium is the the phone it came from. More correct would be Rhodium Manila.
It's available in just about every ROM I have seen released in the past 2 months and there are cabs over at XDA
[APP][COMING 05/08]Gen.Y Manila v2.1 VGA CFC (TF3Dv2.1.38658.0) - xda-developers
Warning though Cab install is quite complicated. It requires a whole bunch of packages to be installed with it because Manila requires them to work. It also requires the Tachi Dialer or Rhodium dialer for full functionality!
It works much better when you cook it into the rom.
So if you want to try it I suggest looking for a ROM that has it or a Kitchen to make a rom of your own.
