Perhaps you should read the spec sheet, msds, and user manual, before making personal attacks?
Please point to any documentation that says the screen is not Gorilla Glass.
I admit I don't know the answer, and the press release is vague. Engagdet.com has read more into this and thinks that all US Galaxy S phones have Gorilla glass.
In multiple threads you reference the spec sheet and manual - but these are not detailed design documents. All they say is tempered glass - they don't say what chips or type of metal and plastic make up the phone either.
Motorola is using Gorilla Glass, but not calling it out in spec sheets on every phone that has it.
I agree that there is little evidence the phone has it, but there is even less evidence that it doesn't have it. All these phones are Galaxy S models, the i9000 is the international, and we know the US varieties. The press releases do indeed imply that all the phones have Gorilla Glass.
Additionally the glass is laminated to the OLED display and thinner then glass in LCD displays - all this points to evidence of Gorilla Glass - it would not make sense to have 2 different display manufacturing lines and standard glass in a thinner package may be to fragile.
If you are going to prove your point, then you better have proof that is less vague and more believable then references to spec sheets and manuals that don't have any real details.
