I am disappointed with the guide - not up to iFixit's usual standards. I got the iPhone open and the battery out just fine, but there were *three* missing hints that would have cut a half-hour from my re-assembly:
1) The connector cover has three short screws and one long one. The video doesn't show which is the long one, so I had to farble around to get the screws back. (The long one is the top-right one, near the hinge on the right side of the phone)
2) There are no hints on the video or in the box about putting the adhesive strips back in. I was trying to get the tab to fold over, but got all wrapped up in the strips. It took a lot of time to fix it, and I still don't know if it's important to fold the tab over or not.
3) There is no information about whether to retain the clear cellophane wrapper that comes on the battery. I took it off - hope that's right.
That said, all the tools were included in the kit, they work as advertised. And the phone's back together, and we'll see how it works...
