The foldable iPhone Ultra finally looks like a real product rather than a rumour, and if you're planning to buy one, the smart money move is to sell your current iPhone before it launches, not after. Here's the short version: when a major new iPhone lands, second-hand values for the older models soften as supply floods in, so the device in your pocket is usually worth more today than it will be on launch day. We've paid thousands of sellers and earned over 10,000 reviews across Trustpilot and Reviews.io, so we've watched this pattern play out launch after launch. Below is what the leaks actually say, and how to time your trade-in so the upgrade costs you less.
Is the foldable iPhone actually happening this time?
For years the foldable iPhone has lived in that strange Apple rumour zone: always coming soon, never confirmed, usually buried between supply-chain leaks and blurry renders. This time the clues feel different.
As WWDC 2026 wrapped and iOS 27 arrived in developer beta, people digging through the code spotted references to things like "fold state" and "angle degrees". That's the language of software preparing for a device with a hinge. Apple hasn't confirmed anything, of course, because in Apple's world products don't exist until they're revealed on stage with cinematic lighting. But when the software starts learning about fold states and screen angles, it gets hard to pretend nothing is happening.
Apple also did something telling during the developer sessions: it nudged designers away from building apps around fixed device sizes and towards a dynamic range of sizes and aspect ratios. That's a very Apple way of saying something without saying it. They don't tell developers to rethink their layouts for no reason.

What we think the iPhone Ultra will be
The device being discussed is often called the iPhone Ultra, and the name tells you where it sits. This won't be the next iPhone for everyone on day one. It'll likely sit above the Pro Max as an ultra-premium, experimental flagship: closed, it behaves like a chunkier iPhone; open, it becomes something closer to a small iPad. One device in your pocket, two experiences in your hand.
Here's what the current rumours point to. Treat all of it as leak-stage, not gospel.
| Rumoured detail | What the leaks suggest | Why it matters |
|---|---|---|
| Form factor | Wider when closed, opens to a tablet-sized inner screen | A genuinely new iPhone category, not just a bigger Pro Max |
| Thinness | Around 4.5mm open, thinner than the iPhone Air's ~5.6mm | Apple's whole pitch is "impossibly thin and premium" |
| The hinge | Over-engineered to nearly eliminate the inner-screen crease | The crease is the biggest visual compromise on foldables |
| Cameras | Wide and ultra-wide, possibly no dedicated telephoto | Space inside a foldable is brutal; the camera takes the hit |
| Internals | A20 chip, 12GB RAM, Apple modem with 5G and satellite | Headroom for AI features more than raw speed |
| Software | Split-screen multitasking, possibly exclusive to this model | The first real reason to bring iPad-style multitasking to iPhone |
| Price | Ultra-premium, rumoured well north of £1,500 | This is a halo device, priced like one |
The interesting one is the hinge. On any foldable, the hinge isn't a component, it's the product. A bad one feels fragile; a good one feels magical. The crease has always been the tell that reminds you the screen folds, and Apple hates that sort of thing. So if Apple is finally entering this market, the pitch won't be "our iPhone folds". It'll be "we finally made a foldable that feels like an iPhone". That distinction is the whole game.
Why this launch is a money event, not just a tech event
Most iPhone upgrades have become incremental for years now: better cameras, faster chips, brighter screens, slightly tweaked designs. Useful, rarely transformational. A foldable Ultra could be the first iPhone in a long time that feels like a different product, not just a better one. And that's exactly why it'll pull people off the sidelines who haven't upgraded in two or three cycles.
Here's the thing most upgraders miss. The excitement of a new launch and the resale value of your old phone move in opposite directions. The moment a headline new iPhone is announced, two things happen to the second-hand market: a wave of people trade in their old models at once, and buyers start holding out for the new thing. More supply, cooler demand, softer prices. By the time the Ultra is actually on shelves, the iPhone you could have sold today is competing with thousands of identical trade-ins.
Worth knowing: a halo device like the Ultra won't replace the standard iPhone line, so your current model keeps its audience of buyers who just want a normal, affordable iPhone. That's good news for your resale value, but only until the new supply lands and the whole ladder shifts down a rung.

Should you sell before the launch or after?
For most upgraders, before. Let's lay it out honestly.
| Sell before the announcement | Wait until after launch | |
|---|---|---|
| Resale value | Usually higher, before supply floods in | Usually lower, more trade-ins competing |
| Certainty | Lock in today's price with a guaranteed quote | Gamble on where prices land |
| Gap without a phone | You may need a stopgap for a few weeks | You keep your phone until the new one ships |
| Best for | Anyone happy to bridge the gap with an old handset | Anyone who can't be without their main phone |
The one honest trade-off is the gap. Sell early and you might be a few weeks without your main device before the Ultra ships. Plenty of people bridge it with an old handset from the drawer, a cheap backup, or a hand-me-down. If being without your phone for even a day isn't an option, waiting is the sensible call, even if it costs you a little on the price. Only you know which camp you're in.
How to lock in your iPhone's value before the rush
You don't have to part with your phone today to protect its value. You just need to know the number and be ready to move when you decide.
- Grade it honestly now. Check the screen switched off under bright light, run a fingernail over any marks, inspect the corners, and check battery health (Settings, then Battery, then Battery Health & Charging).
- Get a guaranteed quote. TechCheck® walks you through specific condition questions and gives an instant quote that's the price we plan to pay, valid for 14 days.
- Test the boring stuff. Cameras front and back, mic, speakers, Face ID, charging port. A fault you didn't know about is the most common reason a quote gets cut.
- Decide your timing. If you're selling before launch, post within the 14-day quote window. If you're bridging the gap, line up a backup phone first.
- Post it free and get paid fast. Free sales pack with a prepaid label, and same-day payment once we receive and verify the device (Monday to Friday, before the 2pm cut-off).
We've all done it: left an old phone in a drawer for a year, watched it quietly lose value, then sold it for a fraction of what it was worth when it still worked. A phone sat in your drawer is wasted value, and on a foldable-Ultra budget that's money you'd rather put towards the new thing. There's a planet angle too: every device we rehome means five trees planted, and a working iPhone passed on beats one going to waste.
When isn't Reboxed the right choice?
If you want the absolute maximum amount of money and you don't mind the work, selling privately on eBay, Vinted or Facebook Marketplace will usually net you more than any trade-in service, ours included. You're cutting out the middleman, so the maths is simple. The trade-off is your time and nerves: photos, haggling, no-shows, return requests, and the small but real risk of being scammed. Trade-in exists for people who'd rather have a guaranteed price, paid the same day the phone arrives, with no faff. If squeezing out the last £20 is worth the hassle to you, sell privately with our blessing.

FAQ
Q: Is the foldable iPhone Ultra confirmed?
A: No. Apple hasn't officially announced it. But the iOS 27 developer beta contains code references to fold states and hinge angles, and Apple has been steering developers towards flexible, multi-size layouts. The signals point strongly to a foldable iPhone in the works, likely positioned above the Pro Max as an ultra-premium flagship.
Q: Should I sell my iPhone before a new iPhone launches?
A: For most upgraders, yes. Second-hand iPhone values tend to soften around a major launch as trade-ins flood the market and buyers wait for the new model. Selling before the announcement usually means a higher, more certain price. The trade-off is you may be without your main phone for a few weeks until the new one ships.
Q: How much will the foldable iPhone Ultra cost?
A: Apple hasn't priced it, and any figure right now is rumour. The leaks point to ultra-premium pricing, likely well above the current Pro Max, because this is a halo device with new folding hardware. Selling your current iPhone before launch is one way to soften the cost of the upgrade.
Q: Will my current iPhone still be worth selling once the Ultra is out?
A: Yes, but probably for less. A halo foldable won't replace the standard iPhone line, so there's still a buyer for a normal, affordable iPhone. The catch is timing: once launch supply lands, your model competes with thousands of identical trade-ins, which softens the price.
Q: How long is a Reboxed quote valid?
A: 14 days. Get a quote with TechCheck®, post your phone within that window, and the price holds provided the device matches your description. After 14 days the price can change, because phone values move quickly, especially around a launch.
Q: Do you accept older or slightly damaged iPhones?
A: Yes. We take iPhones in a range of conditions, including faulty and broken devices, and every device is securely and permanently wiped on arrival. Grade it honestly up front with TechCheck® and the quote you accept is the price you're paid.
