I saw the $49 iPhone 4 deal from Best Buy... question is, does anyone know of any deals on the 4S? I'd be looking for the standard 16GB for AT&T. AT&T has the 4S refurb for $149, but you don't get a FULL warranty - the 1yr starts from the original date of purchase. Does Apple sell any refurb iPhones directly? I'm going to try to call Sam's Club when I get home (we have a membership). Thanks in advance!
