I'm about to buy the 4S soon and I was wondering whether it's better to get the phone at AT&T or at Apple. Would I have better customer care if I buy it at Apple? My brother-in-law just purchased it at Verizon and he had to go back and forth between Verizon and Apple about setting up the phone and it was such a hassle for him. That's why I am asking if it's better to buy it at the carrier or at the manufacturer... Thanks!
