Water Damage - Charger Terminal Coroded but LCI not triggered.
An Apple Genius advised that a single charger terminal had a tiny bit of corrosion although none of the LCI's had been triggered. This was preventing my iPhone 4 from charging. The phone is 8 months old but as the store considered this to be water damage it would cost £130 to repair as the warranty doesn't cover water damage.
Is this right my phone has not been anywhere near water?
iPhone 4, iOS 5.1.1
