Lewis at Unbox Therapy got hold of one of the dummy mock-ups that turn up from China every spring before the next iPhone line, and this year's parcel held the long-rumored folding iPhone, the variant he expects Apple to call Ultra. It's a non-working model, not real hardware, so treat the shape as the story and the internals as unknown.
The form factor is the surprise. Instead of the tall, narrow profile of a Pixel Fold, this one is short and wide, closer to a passport, and folded it feels like a step down from a normal iPhone, fine for a quick call or text and little else. Open it and the logic shows up. The aspect ratio lands near an iPad, which keeps the center of gravity low and stable in the hand and, Lewis argues, lets existing iPad apps map onto the unfolded screen better than a taller fold would. He kept reaching for the same description: a pocketable iPad, an iPad mini shrunk down.
He pulled out calipers. The mock-up measures about 117 mm tall and 84.27 mm wide, and unfolded it sits around 5.2 to 5.6 mm thick, in the range of the iPhone Air. The camera bump is the outlier, taking the body from roughly 11 mm to 16.5 mm at the hump, enough to make it rock on a table. Measurements came off a model sized against an iPhone 17 Pro Max stand-in.
The skeptical read is about who buys it. The name signals an ultra price, and a folded state that feels like a downgrade is a hard sell when the rest of the lineup already covers anyone who just wants a phone.
