adhesvive dot on sim tray, normal?
I pulled out the sim tray of my new iPhone 5 and at the inner end sticks an adhesive dot. Its about 2 millimeter in diameter, white and has a black dot in the middle. I leave it there but I never saw this thing in any unboxing video.
Can anyone tell me what this thing means ?
Possibly an isolation for one of the screws of the circuit board ?
