Hi Carolyn, I am in the same boat as you. I have the parts, just waiting for the courage ! I have already replaced the battery and the trackpad without any issues. Just concerned about breaking anything in the disassembly process. Maybe Apple make these parts so delicate on purpose so that its not user friendly to easily replace without risk (otherwise everyone would be doing it themselves right - no fun or $ for Apple !).. Wish you were here to guide me through the process (knowing that you have already been there, done that ! so to speak !). Cheers Ron

Just broke the two strips of double sided tape. Look at the pictures well here. Pull the strips out a long way (i.e. the length of the battery or more) before you try to move them around the sides of the battery. One they are pulled out that far, becareful as you try to manurer them around the batter as they are now fragile and can break / tear easily. I was able to use a very thin flexible but strong ID card to wedge under the battery and with some effort (careful effort) I was able to pry the tape from under the battery. Half of the tape was still too strong and the battery came out with half of the battery casing left on the bottom case of the phone. Very strong tape the original tape
