Respuesta a "iPhone 3G Glass/Digiter Replacement: Screen Now Black"when you take apart an iPhone 3G/3Gs... do not forget to turn it off before you take it apart. it usually in a way "tricks" your motherboard into thinking your LCD is on when it is not, and and when it is all together your LCD is black. so don't forget to turn it off before you start the repair..
