I went into the Apple Store at BridgeStreet. My 3GS was about to hit one year and the warranty was expiring. I wanted to purchase an Apple Care. The "Genius" looked at my phone with his little light. He then typed the SN into a computer. He then said I could still purchase the Apple Care because he had verified that in fact the iphone was under warranty and he help me register the Apple Care.
I bought the Apple Care. Registered it. Then he looked at the phone again with his little flashlight and said "It appears that your lower water sensor has been activated." I asked him what that means. He said that means your warranty is VOID.
VOID!!!!!!
He just sold me an Apple Care knowing the damn thing was WORTHLESS!!!!!!!
