Hola, ok so i have about 4 dead pixels and my visual voicemail is not working anymore so i am going to pay a visit to Apple tomorrow but i wondering if they decide to give me a new one (i bought my iphone in Las Vegas, im currently in college in San Francisco) would that pose a problem cuz i kno they have digital receipts there and stuff but will i have to have my mom send the receipt or go back to Vegas or could they just do it at an Apple store here?
