Sales of the iPhone hit an all-time high in the final three months of last year, tech firm Apple reported on Thursday. Revenue rose by 16% compared to the same period last year to $144bn (£82.5bn) - the strongest growth since 2021 - thanks to a jump in sales in China, as well as Europe, the Americas, and Japan. However, sales in other parts of the company were less positive. Wearables and accessories, which include things like the Apple Watch and AirPods, fell by roughly 3%. Apple chief executive Tim Cook said the iPhone's boost in sales meant the firm was in supply chase mode.

The issue has gathered broad support from technologists, farmers, military leaders, and politicians on both sides of the aisle. It is popular with just about everyone--except the companies who stand to gain if the parts, instructions, and tools necessary to fix their products remain under lock and key. Three US states passed right-to-repair laws this year, including in heavily Republican states like Texas where the measure received a unanimous vote in both the House and Senate.

Your choice is applied immediately, and you can see the change in the preview window. However, the difference isn't as pronounced as you might expect across every part of iOS.
