@ Tony Sossong thanks a lot

Grrrr. I rebuilt my iphone and forgot the little silver ring around the camera... found it today in the old backing.

IMPORTANT IF MOVING TO NEW BACK HOUSING DO NOT FORGET:

1. little speaker and mic grill things on the bottom of the inside of case.

2. little silver camera ring that is visible from outside and might blend in with back of black iphone from inside.

3. Silver ring around 3.5mm earbud/headphone port. (may stick to chrome bezel)

There are little grill things that might stay on the case if they do take them off and stick them back on this part. DO NOT FORGET TO REALIGN WHEN BUILDING IPHONE!

What type of glue should i use?
