You really avoid this product contrary to previous comments. LCD comes with the tools necessary to disassemble the Iphone.Après trying mounting the screen, I appear connectivity of my damaged screen and that of the new screen. It is not at all the same when I has a well Iphone 3G No. A1241 and the announcement states that the assembly is provided for a 3G Iphone frame. I'll return the product and get a refund
