I bought one. It was a scam, an ordinary 1430mah battery with a label on it saying it was higher. if you google 'iphone reports high capacity battery as 1430 mah' you'll find plenty of videos by people who got ripped off.
Oh, my god. It worked. I wish I had discovered this before I actually fried my motherboard trying to fix it. To those who don't understand, I didn't get it either, but it's exactly what it sounds like. Put the ribbon cable where you wanted to go, put a long piece of sticky tape on the back and press it down with your finger and then pull the tape in the direction that you want the ribbon cable to go.if you move the tape around and do this side-by-side, you will see, it will slide the ribbon cable into the harness, even though it seems like that would never work.
