I received a 'AppleCare+ Proof of coverage certificate' email from Apple for my new iPhone 6s Plus. I noticed the dates being off by few days. I expect the warranty to be for 2 full years from the date I receive my iPhone. As the expected delivery date is Sept 25, 2015, I expect the warranty to be effective until Sept 25, 2017. However, the coverage letter states the warranty being only until Sept 21, 2017, 4 days before what it should be. Anyone else seeing Apple short-changing on warranty ?
