Power switch stop working. Felt no spring/tactical feel to switch.
Went ok. Few differences from a 4s. IFIXIT instruction are very useful. I did find that the iPhone4 instructions were less detailed than the 4s. When lose parts would come into play the 4s instructions would call them out. This was not always the case with the 4. When I finished the 4(replacing the power and sensor cable) I discovered a rubber bumber(I think) that may have been used for covering a tight corner at bend point. I found it after I closed up the phone, no idea where it came from other than the phone because it was not there before I started. Over all it went good. Just wish I knew where that part belonged?
I did order a set of screws for the phone, because I was replacing a display in a phone that was serviced by someone else and it was missing one or two screws. The issue I have with the set of screws I received was that they did not mark/ describe (mark with size ) each screw. I do not own a micrometer and I could not visably desern the differance between screws.
