If you want to know if your iPhone is new or remanufactured just look at the model# listed in settings/general/about. If the number starts with a M or P it is a new retail model. If it starts with a N it is a remanufactured phone by Apple. If it starts with a F it was refurbished by a carrier or 3rd party vendor..So your opinion is based on your experiences and my opinion is based on mine, but for some reason the information I was given was flawed and yours is correct. Got it.
I too have dealt with AppleCare and store employees on multiple occasions. I have bought every iPhone since the first release. I have had to replace just about every phone I have had since the iPhone 5, AND I was provided with the information I am sharing over several years by multiple employees.
I guess there must be some big conspiracy in play to hoodwink me into thinking otherwise. I agree that as time goes on and stock becomes limited, refurb'ed units could make their way into the pipeline, but so far no one at Apple has shared that information with me. Thanks for sharing your opinion.
