I just photographed these on the European continent in a mom and pap mobile shop. Shrink-wrapped. The shop assistant could tell it for sure sure, but maybe they are from the UK. There were also 5s models, just not so photogenic than the 5.
The question is, if I want a reliable source for these, not the mom and pap mobile reseller, which is a good place to buy these anywhere (in Europe, or possibly elsewhere, too).
Other OS, null
Look on the UK Apple Store - https://www.apple.com/uk/iphone/ or go to the bottom of the store page and change to whatever country you like.
And if you specifically mean certified pre-owned iPhone's, there is no such thing at all. Apple does NOT sell refurbished iPhones at retail, nor do they authorize anyone to do so. Individual companies may sell "certified" pre-owned but you would have to ask them what the heck they actually mean by that. Certified pre-owned iPhones are NOT available from Apple nor from any Apple Authorized reseller.
The only legitimate source of "pre-owned" iPhones in the retail market would be carriers who offer their own in-house refurbishment (which is NOT Apple factory refurbishment). But they should not be packaging the devices to appear as if direct from Apple.
The fact they are even printing that on boxes apparently meant to mimic authentic Apple refurbished products makes me think they are pure illegal scam artists.
What does the warranty have to do with bogus claims by non-certified sellers?
