Debris or Corrosion Removal in iPhone PortsDebris or other contamination could prevent iPhone from proper function, connection, charging, or testing and should be removed if possible. Use a lighted otoscope or lighted magnifying glass to check the iPhone:
1. Dock connector
2. Headset jack
3. Speaker opening
4. Microphone opening
Important: iPhone Corrosion indicates exposure to liquid and is not covered under warranty. If debris or contamination is from an external cause, any resulting non-operation, malfunction, damage, or cosmetic damage is also not covered under iPhone warranty.
Note: Lint or other foreign debris should be removed with a compressed-gas duster, and if needed, an anti-static brush and or anti-static tweezers, before connecting cables to your iPhone
