iPhone 4 Rear Panel
I was unable to find a replacement for the Atlas subwoofer it uses and ended up "recycling" the whole thing :( I've since replaced it with the the Klipsch ProMedia 2.1s and love them.
The *used (but verified)* lightening connector I ordered from iFixit was missing three things:
- Adhesive on the back of the screen connector
- Tiny foam square on the back of the antenna connector
- Rubber mic-cover
The first two can be carefully cannibalized from the broken one, and the third must be carefully removed from the broken one and refitted onto the new one. Take great care in doing this! It's a bummer iFixit doesn't provide any instructions for these steps!
