Replacement screens can be bought for around $10, I replaced my friends 3GS screen and digitiser and it was pretty easy. I just bought some screen protectors for the iPhone 4 which I have given to my wife, but I'm thinking with all money I have spent on screen protectors over the years, to preserve its resale value, might be better spent on just eventually buying a new screen. However I'm not sure about the quality of the glass. Does anyone know if its possible to get replacements made of actual Gorilla glass? If so, how much does it cost? Thanks.
