It seem like the real wozwebs is selling this phone elsewhere and it's actually a 64GB and not a 128GB.
Something poked fishy about the photos and a simple image search for 'wozwebs iPhone' produces some interesting results.
For those in question, here's the link to the real seller's advert.
If anyone wants they can contact the real wozwebs to find out if it's the same guy although all pointers are indicating that he's clearly not.
In other words, stay far away from this...
