Cupertino, CA – June 13, 2025 — Apple has quietly rolled out a revised version of iOS 26 beta 1 to developers just days after its original release, targeting only iPhone 15 and iPhone 16 models. While the update isn’t labeled as beta 2, the new build number (23A5260u) replaces the earlier version (23A5260n) for supported devices.
Why Did Apple Push a Revised Beta?
Although Apple has not officially detailed the reason for the update, experts suggest it may patch a critical bug, security flaw, or even remove unreleased product code unintentionally included in the first build. The quick turnaround highlights Apple’s growing focus on stability and developer readiness during the early testing cycle of a major iOS release.
Who Can Install It?
The new beta is only available for iPhone 15 and iPhone 16 models. Owners of iPhone 14 and older devices will not receive this revised build and should continue with the original version until further updates are made available.
What’s New in iOS 26?
Unveiled earlier this week at Apple’s WWDC 2025, iOS 26 introduces:
- A sleek new Liquid Glass design across the OS
- Revamped experiences in Messages, Phone, Safari, and Music
- Enhanced features for Photos, Camera, and Apple Intelligence tools
These new elements aim to bring greater personalization, privacy, and productivity to everyday users.
What’s Next?
While the updated beta remains exclusive to developers for now, public beta testers can expect access in July. The official launch of iOS 26 is expected in September, alongside other Apple OS releases including iPadOS 26, macOS 26, watchOS 26, and visionOS 26.
Should You Update?
If you’re a developer using a compatible iPhone, it’s recommended to update to the latest build to avoid potential issues in app testing. For general users, it’s best to wait for the public beta or final release to ensure a smooth experience.
