So my iPhone 5s fell off of my lap when i was sitting down and fell face down onto the floor. In short the screen is cracked all over. Im looking to replace it but I can't exactly afford $270 to get apple to replace it, I paid just $30 more for the phone new a few weeks ago. I looked into replacing it myself but buying replacement screens are somewhere between $220 and $250 for an iPhone 5s screen. My question is can I use an older iPhone 5 screen which is around $150 on my iPhone 5s as a replacement?
