iPhone 4 Rear Panel
A couple of additional pointers might be helpful...
1: I did not get all of the adhesive out from under the battery. As a result, I bent the heck out of the battery & ordered a new one, not trusting a bent one. A mention of whether it would be safe would be nice.
2: I found it impossible to get the clip from step 7 back on. I left it off. If there's a trick to this, it would be nice to have that extra instruction with the reassembly instructions, rather than "reverse order."
3: While this is always a good idea, in the process of trying to get something done, it's easy to forget that you need to remember which screws go back where, especially the 3 different-sized screws from step 10. What an evil thing Apple did there! I laid the bracket upside-down on a piece of tape, and oriented the screws around it so I'd know where they go back upon reassembly a week later. A suggestion of doing something like this might be helpful.
4: I love my iFixit toolkits! But including a pair of tweezers in it would be helpful.
