FWIW, I asked Welectronics where they get their supply from for this particular model or whether they swap cases. They confirmed it's 64 GB and said:

"It will be the ME ( Middle east ) version .
All the phones we sell are brand new and sealed . we just sell phone dont know how to fix up on any of the devices."

Not sure what to believe now. I've seen Welectronics mentioned several times in various forums and no one reported being scammed. Has anyone heard of or seen such Middle Eastern N9?
