Broke original back of iPhone4. Needed a quick fix to repair.
I received the shipment, but the part covering the lens was cloudy on the inside which resulted in unclear photos (yes, I did remove the small round plastic cover on the outside first). I called iFixit and they gladly sent me a replacement, and that one was perfect. Thank you!
If you have any problems, just give them a call.
