I need a Front LCD Display Screen Touch Digitizer Assembly Frame for Iphone 4S Black, where can i buy it ? can i it by website? what ? thanks

Anywhere you can find it via the obvious Google search. It won't be from Apple, but will be a generic replacement.

Why are you throwing away any future chances of out of warranty replacements when you drop or drown it? Apple will give you a warranteed replacement phone for $199 (in the US, roughly the same in your country)
