After cracking the glass on my iPhone 3GS, I ordered a replacement screen. I ordered one off of eBay, and other than some stripped screws, I had no real issues installing it... Until I went to connect the flex connector (?) for the digitizer. There are 3 connections that need to be made between the phone itself and the replacement screen/digitizer. I believe that the connector that is attached to the replacement screen itself (the one that sticks out of the top) is for the digitizer - correct me if I'm wrong! Anyway, this one didn't want to snap into place. I found that when I held it down with a small tool, the touchscreen was semi-responsive, but as soon as I took the pressure off, the connection was lost, the connector popped up, and the touchscreen stopped working. The connector on the original (broken) screen looks just slightly different, and still snaps into place. So I figured I just got a cheap part. I ordered a second one, hoping I'd have better luck. This time, I ordered it from Amazon.com. Same deal. It didn't want to "snap" into place the way the original connector did. I don't want to keep spending money on these parts when I don't know if they'll work with my 3GS or not. How can I order a part that is very similar (or identical) to the original part? Any assistance here would be much appreciated - thanks in advance!
