Sorry I missed this!That's weird for it to not have the gorilla glass. I know in Canada all high end Samsungs have it.
Did you have issues with your Galaxy S? Mine was always freezing, going into SOS mode, and probably 10 other things I can't think of right now.
No issues with my S but my brother inlaw's Galaxy S has been pretty bad for a while. It's the Verizon flavor of the S. Mine was always great and so far, the Skyrocket has been awesome.
As for gorilla glass, it's up in the air. No one knows. The regular S2 has it so why wouldn't mine? I can say that the screen has been extremely durable for all the pain I've put it through.
Oh and ICS is awesome!
