Iphone 4s cost 837 US$ or 629,00 in germany. I think that's way too much compared to 649$ american price. 649 is way cheaper. I wonder if I could buy the iphone from US ? How is the Apple warranty ? If something happens to the phone can I exchange it at the Apple Store in germany ? As I read here on forums, one of the reason to buy from Apple is the legendary phenomenal customer service and care. So would that work ?
