Hello, I bought an iPhone 5s in November and I exchanged it for a new one in a white box. I have two questions : - Does this iPhone is refurbished or new ? ( I exchanged it in early November) - I saw on the web that all the people who had exchanged their iPhone 5S for a new one with the "white box" had a serial number with "C3" at the beginning, which means it has been manufactured in C3 factory, in China. Do all the iPhone 5S exchanged in white boxes are manufactured in C3 factory or did you receive an iPhone with another serial number ? Thank you for your answers !
