The most recent leak regarding the iPhone Ultra reveals almost everything, featuring a highly anticipated iOS function.

      Jon Prosser, the leaker whom Apple is suing for allegedly disclosing iOS 26 trade secrets, has released another video on his YouTube channel, Front Page Tech, presenting what he claims might be the final design of the rumored iPhone Ultra.

      In addition to showing slightly updated renders, Prosser cites developer code from iOS 27 to support his assertions, specifically regarding the iPhone Ultra's existence and a new feature that users have been requesting for years.

      So, what does the latest leak reveal about the iPhone Ultra?

      The renders depict a book-style foldable, which Prosser refers to as a “chunky iPhone” when closed and an “iPad” when opened, information we have been aware of for some time. When unfolded, the device could be just 4.5 mm thick, making it slimmer than the iPhone Air, which measures 5.6 mm.

      The body is made of titanium and features what the host describes as an “over-engineered hinge” intended to create a nearly creaseless display. Apple has reportedly been working on this technology for an extended period and has encountered a few challenges.

      As shown in the video, the supposed iPhone Ultra is expected to be available in two colors: white and black (or a dark gray finish). Many of these specifications aren’t entirely new and have been reported by various sources.

      However, there were some smaller details that caught my attention, which weren’t heavily highlighted in the video.

      What has changed since the December leak?

      Front Page Tech released a similar video in December 2025, referring to the foldable as the “iPhone Fold” instead of the iPhone Ultra. After comparing both videos, I noticed several differences.

      In the previous video, the power button (which includes integrated Touch ID) was positioned at the top of the smartphone, directly above the camera bar (with the display facing forward). The new renders, however, show volume buttons in that same spot. Additionally, there’s now a speaker grille on the top frame.

      The power button has been relocated to the right side, where it typically resides on an iPhone, but is now positioned on the lower half of the foldable. This deviates from the usual iPad button layout that users are accustomed to and may require some adjustment.

      Another significant change is the new, more compact camera visor. Instead of spanning the full width of the rear panel, it now only covers the area around the dual rear-facing camera module, raising the sensors above a flat panel and contributing to a more streamlined appearance.

      What about the new iOS feature?

      Prosser asserts that the iPhone Ultra will introduce split-screen multitasking to iOS, although it will likely be exclusive to the foldable model. This means that existing iPhones may not receive it, even if they support iOS 27.

      Apple seems to be preparing for this in the iOS 27 code, with terms like “fold state” and “angle degrees” appearing in the developer beta.

      Following WWDC 2026, Apple also advised developers to get ready for a wide variety of screen sizes and aspect ratios. If Prosser's claims hold true, the iPhone Ultra would be the first iPhone capable of running two apps simultaneously.

      Other specifications surrounding the device, such as the A20 chip, the C2 modem with satellite-based 5G support, and a price exceeding $2,000, remain consistent. It is still uncertain whether the iPhone Ultra will come with Touch ID and a Camera Control button, but a launch in September 2026 alongside the iPhone 18 Pro and iPhone 18 Pro Max appears probable.
