I went to my local apple store with my iphone trying to get it returned under warranty because i have been having issues with my WiFi on it. It sometimes will just drop the WiFi on its own. The problem arose once i stepped up to the genius bar, I hand over my phone to the macgenius and he says, whats wrong with it? I explain it to him, then he flips over my phone, where i scratched the phone and put in a .3(3/10)mm dent and says: "How did this happen?" I say well it fell into my couch and landed on a metal bar in there. He then replies: "Well this voids your warranty, its probably the reason that your WiFi isnt working". So it was a no to the warranty exchange. I bantered with him a moment saying that the dent isn't even anywhere near where the WiFi card is in the phone but he wouldnt hear it. Well i left the store and have been using it for the last few days, and then my friend told me i should send it in via mail because they would understand that it isn't the cause of the problem and that they are less strict then the apple genius bar is. My question to you guys is: Is what my friend said true? do you think i have a better chance of getting my warranty worthy (IMO) phone repaired(Replaced) via mail? Thank you ahead of time for your answers.
