Isn't there a Gingerbread Beta V2 out?

The only GB ROM out is the Infused ROM. The v2 is because it is the second big release of Infused. It's still in it's first BETA stage though. Head over to XDA, there's a thread in the development section.
 
The V2 is the gingerbread version of it. Made so by the dump from our Canadian friends. Although it still is in beta as well
 
It is beta but it is great. Been running it since it came out... Only had a couple minor issues that were well compensated for.
