Do this then, and I bet it'll work. Take it back to the store and demand a refund of your money if they won't exchange it for another new one. Regardless if they can't replicate what's happened to u at home with ur device. Once they see u want ur money back, that'll change their minds and they "should" gladly give u another new one then. U are still under the 2week return policy. Don't wait, seriously, cuz if u do, u are gonna have to go thru warranty and all they will do is give you a refurbished unit. Nah!! U don't want that. U bought it brand new and want it exchange noes for another brand new one. Those stores try to hold out cuz returns under 2 week policy goes on them, if they get u past 2 weeks, then it falls on the warranty, meaning manufacturer. SO DON'T WAIT ANY LONGER! Forget waitng for new iOS upgrade, it should work perfect right out the box. Don't wait and sell itself short n u be even more angry that u did.
