Jon Prosser, the leaker Apple is currently suing for allegedly leaking iOS 26 trade secrets, has published yet another video on his YouTube channel called Front Page Tech, showing what he says could be the final design of the purported iPhone Ultra.
Along with slightly different renders from last time, Prosser also points to iOS 27 developer code to back up his claims, particularly regarding the existence of the iPhone Ultra and a new feature that iOS users have been requesting for years.

So what does the latest iPhone Ultra leak actually show?
The renders show a book-style foldable that Prosser describes as a “chunky iPhone” when closed and an “iPad” when opened, something we’ve already known for a while. When unfolded, the phone could measure just 4.5 mm, making it slimmer than the iPhone Air at 5.6 mm.
The titanium body pairs with what the host calls an “over-engineered hinge” designed to produce a near-creaseless display. Apple has reportedly been developing the technology for quite some time and has also faced a couple of setbacks.

As seen in the video, the purported iPhone Ultra could come in two colors: white and black (or a dark gray finish). Most of these details aren’t entirely new and have been echoed by several different sources.
What stood out to me, however, were a few smaller details that didn’t get much attention in the video.

What’s changed since the December leak?
Front Page Tech also uploaded a similar video in December 2025, calling the foldable the “iPhone Fold” instead of iPhone Ultra. After watching both videos side by side, here are some changes that I’ve noticed.
While the previous video had the power button (with integrated Touch ID) at the top of the smartphone, right above the camera bar (with the display facing you), the new renders show volume buttons in that position instead. There’s also a speaker grille on the top frame.

The power button is now located on the right frame, where it normally sits on an iPhone, but on the bottom half of the foldable. This isn’t the typical iPad button layout everyone is used to, and it may take some adjustment.
The elephant in the room is the new, more compact camera visor. Instead of covering the entire width of the rear panel, it extends only around the dual rear-facing camera module, elevating the sensors above an otherwise flat panel and creating a more seamless look.

What about the new iOS feature?
Prosser claims the iPhone Ultra will bring split-screen multitasking to iOS, though it would reportedly be exclusive to the foldable. That means your current iPhone likely won’t get it, even though it supports iOS 27.
Apple appears to be laying the groundwork in iOS 27 code, with strings like “fold state” and “angle degrees” surfacing in the developer beta.
Following WWDC 2026, Apple also instructed developers to prepare for a dynamic range of screen sizes and aspect ratios. If Prosser is right, the iPhone Ultra would be the first iPhone to properly run two apps side by side.

Other claims about the phone, such as the A20 chip, the C2 modem with satellite-based 5G connectivity, and a price tag north of $2,000, remain similar. Whether the iPhone Ultra will ship with Touch ID and a Camera Control button remains unclear, but a September 2026 launch alongside the iPhone 18 Pro and iPhone 18 Pro Max seems likely.
