Well I bought it in like.. January of 2010. & I was 99% positive that it was the 3G version. But as I download the iOS 4.0 (not install) from iTunes, it says that I'm downloading the 2G version of iOS 4.0. As I use Sn0wBreeze's 'f0recast' tool, it says that I have the 2G MC Model. Could someone elaborate for me?
