I'm asking this question for my cousin.
So, he just bought an iPhone 4 off ebay with warranty. However, the phone's volume button doesn't work. After he brought the phone to Apple to repair, they claimed the phone had contact with water and their warranty won't cover it.
My question is: could water damage affect the volume button in such a way it render it useless?
Thanks!
Added (1). Well, I can say it is very hard to sell a phone with defect at a suitable price. Even if he were to sell the phone back at the price he bought at, he still has to pay a cut to eBay and paypal. If he leaves a negative feedback for the seller, the selller is going to do the same to the buyer -- eBay really sucks in this area…
