"Is the display the same for the 4 and 4s?"に関する回答okay, I used a iphone 4s screen on a iphone 4. I cut off middle leg on the right side of the screen so it will fit. I wasnt able to screw the two top corners in because the holes of the screen do not go up enough. My screen still turns black but the phone still turns on and makes noises, calls, vibrates, etc. Is there something I did wrong? I have been searching and I cant find anything. I've tried shutting it on and off, holding the home button after for several seconds, and taking the whole thing apart and checking for debris and the same thing happens...black screen. (1) when I was cutting the leg off the screen, I did accidentally cut the inside of the screen and my friend threw the phone on the ground from the second floor before i performed surgery because he was angry.
