Done in 15 minutes! I read the instructions, then all the comments and this is what I did. The suction cup did the job of raising one corner of the bottom edge of the screen. I was careful to insert the pry tool under the entire display not just the glass. I used the business card they included in the kit to hold one corner up while I worked on the other. Once both corners were loosened, the entire display opened easily with little force. Then I skipped steps 6-9 and instead had my partner hold the screen at a little less than 90 degrees. Removing the battery proved to be one of the difficult steps. I pried from the outside edge opposite of the lower pry mark indicated in the instructions. With a little constant pressure it finally loosened. Re-attaching the new battery connector took a little patience too, but once it snapped in place, my phone was completely reassembled in short order. It looks and works exactly like it did before except that the battery does not die at 30% at 11 AM. Thanks Ifixit!
