A new open-source iOS utility called 3105 is gaining attention because it brings several Filza-like features to iOS 26.0–26.6.1 and iOS 27 Developer Beta 1–4/Public Beta 1–2. Unlike a traditional jailbreak, 3105 doesn’t install a bootstrap, daemon, or persistent jailbreak. Instead, it focuses on app-container management, portable patching, cache cleaning, and PosterBoard wallpaper customization.
The project is publicly available on GitHub under the GPL v3.0 license, allowing anyone to inspect its source code.
What is 3105?
3105 is a native Swift iOS application that provides advanced file management inside app containers using publicly documented and research-based techniques.
According to the official README, its main features include:
- Browse app data using stable bundle identifiers instead of changing container UUIDs.
- Copy, move, rename, delete, and organize files.
- Create and extract ZIP archives.
- Import and export portable .3105 patch packages.
- Clean Library/Caches and tmp folders.
- Install and manage PosterBoard wallpaper packages.
- Support English, Vietnamese, and Simplified Chinese interfaces.
The project specifically states that it does not install a persistent jailbreak, bootstrap, or daemon, although it still relies on device exploits for supported versions.
Verified compatibility
The official compatibility list is broader than what the X post mentions. iOS Version Support iOS 17.0–17.7.x Supported iOS 18.0–18.7.1 Supported iOS 26.0–26.6.1 Supported iOS 27 Developer Beta 1 Supported iOS 27 Developer Beta 2 Supported iOS 27 Developer Beta 3 / Public Beta 1 Supported iOS 27 Developer Beta 4 / Public Beta 2 Supported
The project intentionally marks unlisted iOS 27 builds as unsupported rather than assuming compatibility.
Installation limitation most posts don’t mention
This is the biggest catch.
3105 cannot be installed through SideStore, AltStore, LiveContainer, or 3uTools for full functionality.
Instead, the project requires:
- an enterprise-signed installation, and
- a specific bundle identifier (
com.apple.mobile.MobileHouseArrest) that enables its workflow.
This matches the compatibility notice shown in the screenshot shared on X.
How does it compare to Filza?
The standout feature is its portable .3105 patch system, which survives app container ID changes between devices.
Is it safe?
Since the project is open source, developers can inspect its code and build it themselves. The README also includes several warnings:
- Back up your device before using it.
- Only modify data you own.
- Avoid sharing logs or app containers containing personal information.
- The app uses device exploits, so compatibility depends on specific iOS builds.
Open source doesn’t automatically guarantee safety, but it does make the project more transparent than closed-source alternatives.
