I'm looking to buy an old iPhone 4s (or higher) to test out an app I'm writing, so I jump on eBay and have a look around.
A fair chunk of the phones go for over $100 AUD, regardless of state. I understand there'd be a rather big "for parts" market out there, but what strikes me as amusing, are the descriptions.
One person said that the Wi-Fi was busted and that the phone couldn't make or receive phone calls, but was otherwise fine, another said it the screen was cracked but otherwise fine (the glass had cracked and they'd just idly pulled out shards while bored), yet another said "minor crack in the glass on the front", and the crack descended half way across the screen, and 1/4 of the way down. On an 4" phone, that's not minor!
So yeah I'm reminded of Reverend Lovejoy, advertising the card table
EDIT: Not to mention when you browse eBay listings, literally 95% of the listing is taken up by what feels like an Apple advertisement, listing the specs, showing a video (which is a promotional video, and not an indicator of the currently listed phone), plus a rating system at the end with people giving reviews for iPhones in general, not that specific iPhone or seller. So you have to scroll through a ton of crap just to find that the seller either hasn't included a description, or the description is just "chip in corner" and nothing else.
