After having dropped my iPhone 4 while in its case and finding out the screen was cracked, I was determine to find a fix. Before when I had an iPod touch, 2nd generation, the screen was easily removed. I took out the pins from the front of the screen of the iPod; and in the iPhone 3 and 3GS's case the screen popped out after removing two screws. I assumed it would be as simple as that having done the procedure plenty of times for my friends broken gadgets.
After buying this expensive phone my self and having to pay for yearly internet usage, I figured, I would take great care of it and skip the care protection plan. I did take extensive care of it, I used a screen protector along with a case and never had any problems until a few days ago. I was sitting on a bench out side of school (bench was about 1 and a half feet from the ground) with my phone laying beside me I must have gone to grab it, but the phone slid off the bench and hit a mulch surface.
I assumed one little drop couldn't do harm to a helicopter glass grade panel but when I went to pick it up I saw the ungodly crack under the screen protector. I am trying to say that this was an unlikely hit to the phone. As soon as I got home, I looked up replacement parts for the phone and a quick tutorial. My recent fixes with previous Apple products gave me enough experience to say: BUY A FULLY ASSEMBLED REPLACEMENT PART. The vendors on eBay and sites like those are not out to help you, they are just looking for your money. You need to make sure you do the research before you buy the parts. So be smart when you buy the replacement; I proceeded to buy a fully assembled retina display and glass piece. THESE PIECES SHOULD NOT BE BOUGHT SEPARATELY. I STRESS THIS BECAUSE APPLE DOES THE LAMINATION OF THE TWO TOGETHER WHICH IS IMPOSSIBLE TO DO BY HAND. If you have ever done an Apple product repair such as iPod touches or iPhones, you would think that the LCD and the Glass are two separate pieces. Instead on the iPhone 4, Apple decided to use lamination of the two to reduce the glare. That feature was effective and took out the variable of dust particles getting in to the phone but makes the replacement of one twice the amount of money.
