My iphone 4s screen was broken and cracked on the front and back. Got quoted $50 for each side so $100 total. About and hour later they were done, however the guy that installed it accidently cracked the glass on the front during installation while pushing it in. He said that was his last glass screen unless I wanted to wait a week. He knocked $50 off the price and I paid half as the crack he made was internal and just put a small line through it from top to bottom that wasn't too noticeable and I needed my phone immediately as I was heading out of town the next day for a week.
About 3 hours later I reach into my pocket for my phone and pulled it out. As I take it out of my pocket the front screen and back screen both come apart!!!!!! I noticed that the guy who repaired it forgot to put the screws back into the phone that hold it together! Who does that?! Luckily I was at the Kierland Commons and walked into the Apple Store to see if they could replace the missing screws. They did for free thankfully, did not expect that from Apple.
Now after about a month of having the screen "fixed", their are two huge cracks running through the screen after my phone rolled off the couch and onto the carpet taking a massive 10 inch fall, haha. I don't what they replaced my screen with but it has the durability of paper mache.
This should of been expected from a place that looks on the outside to be across between a pawn shop and a bail bond agency. Lesson learned, just awful. You've been warned. Take your chances with the Apple Store, atleast they replace the screen with Apple glass.
