This is how much you can earn if you trade-in or unlock your old iPhone for the new 6s/6s Plus
Want some more advice? US customers must consider whether they should unlock their phones or not prior to selling or trading them in, a topic that we've touched upon in the past. According to the most recent data, consumers could earn as much as $130 more by unlocking their iPhone 6 16GB, or up to $55 more for an unlocked iPhone 5 16GB, as long as the phone isn't locked to Verizon - in which case, you're better off keeping it locked and throwing away the key!
UK customers, meanwhile, should compare offers by the various recycling companies running on the island, as it turns out they could potentially earn up to £62.50 more by comparing iPhone 6 prices online, up to £52.10 more for iPhone 5s prices, and up to £43.40 for the iPhone 5.
In the graphics below, you can see illustrations of top trade-in prices on CompareMyMobile and GadgetValuer, and price differences (locked & unlocked) for US consumers and UK recyclers.
