After all the excitement and waiting over a month to get it I am sending my 5S back to Apple tomorrow. Was working great first 2 weeks, then touch id started playing up... Just don't understand, sometimes it works, sometimes not. Hopefully get it back or a new one asap, anyone know how long they take to repair it? Yeah I called and they said they would ship a box to return it on Friday and received it Saturday. Anybody else experiencing this?
