I've been watching the availability of 128GB iPhone 6 in the Chicago area and yesterday most stores started stating Available today Yeah. I'd rather pick up than order.
I'm guessing that's about the end of Apple catching up, but still there's that 128GB issue. Did they resolve that with different chips or some other redesign? I'd wait a couple more weeks if that's what it would take.
There isn't any widespread issue.
Maybe it was just a defective batch of NANDs.
Btw the 128 Gb model is just too expensive for more, so I settled for the 64 Gb (it's 839 in Italy, Like 1020$).
