How to identify Refurbished iphone 6s plus
Hi, i am buying an iphone 6s plus and i was wondering if there is any way to know if an iphone 6s plus is original or refurbished , can the serial number identify if it has been refurbished , like i read serial numbers starting with M are new retail units , N are replacement , F are refurbished ones , is that true for 6s plus or is there any other way to identify
iPhone 6s Plus, iOS 9.2.1
