There was an understandable hue and cry when Samsung announced that the original Galaxy S would not receive an Ice Cream Sandwich update. Manufacturers love for their custom UIs had won again, and all that Samsung promised to calm down the mob was a value pack.
But, as we all knew, the developer community wouldnt let such a popular phone die an early death. There are a few ROMs on XDA already, and users can also now get a taste of CM9 with their nightly builds.
Do remember this is for the international (and the Brazilian) version only. The builds for the various US versions shouldnt be that far off, though.
