In certain parts of the world if you want a good deal you go to the local mom and pap cellphone shop, where they sell used and new, 'like new' and everything imaginable in between. (Whether it is wise to buy anything from these kinds of shops is another issue: that is not the question here.) I understand I can check my warranty status AFTER I bought the device here: https://selfsolve.apple.com/agreementWarrantyDynamic.do Simple as that. My question here is if I want to look like a smart inspector in these shops is there a way I can check if a particular device will be eligible for official warranty BEFORE I actually buy it? For pre-owned devices it's easy: say, someone sells a 2 months old phone you check if it still caries 10 months of Apple warranty. But what about the phones they sell as 'brand new' or 'like new'? What is the trick, why are they cheaper than other, more reputable looking sources?
