[Q] Build prop question

[Jmac9]

Many moons ago, I read somewhere that in order to get full market access, we had to change a few lines in the build prop to basically "trick the market" into thinking this was a different phone. Some apps are not campatbile with the stock Fassy but when rooted with custome Roms it is.......ex Crackle TV.

Had it set for a long time as a Galaxy S or a Nexus. Well during multiple flashes in ICS I somehow lost the info and my old brain can't remember what to change. Anyone have that info?

Thanks!
