I hope what I learned about broken screens on iPhones will help others. Here goes. My phone: an iPHone 4 with a cracked glass My solution: I bought a replacement assembly from Gadgetown on ebay for $25 and change. The reviews were all great. When it arrived, I installed it with no trouble by watching a youtube video at http://phonedoctors.com/video/. Success. But with a big caveat. The screen was just not as good a performer as the original Apple retina LCS. I knew this might turn out to be the case, but for $25, I was wililng to try. The new screen "blacks out" in dark areas. Also, it' s very hard to find an optimum viewing angle. Don't get me wrong - it works and it's pretty good and it was only $25. It's just that it's very hard to downgrade one's expectations after becoming accustomed to the very, very high quality of the OEM screen. Enter another, better solution. Since my original Apple retina display still works, albeit with a broken glass attached to it, I am going to send it off to PhoneFixPro who will remove the broken glass and fuse a new glass to my still-functioning Apple LCD. Cost = another $25.00 Lessons learned: It's not hard to disassemble the iPhone. Just takes a while - 2 hrs. (but i enjoyed it. It's absolutely true that Apple does't let anybody sell OEM parts. Everything is aftermarket, 3rd party.. Those aftermarket screens aren't too bad, especially for $25. but they sure aren't Apple. The same $25 would be better spent buying only what you need, and keeping your original Apple LCD. I'll post again when I've reinstalled my original screen.
