Tenorshare has released an update to its 4uKey iPhone Unlocker that adds support for the newly launched iPhone 18 series and expands Activation Lock compatibility for devices running iOS 18 through iOS 26.1. The move matters because it gives users of Apple's latest hardware and recent operating systems a potential route around activation locks, a persistent pain point for second-hand buyers, businesses managing refurbished fleets, and individuals locked out of their own devices. The update also underscores how third-party software vendors are racing to keep pace with Apple's rapid iOS release cycle.
The latest 4uKey update adds the iPhone 18 series to its supported device lineup. Users with newer iPhone models can connect their devices to 4uKey and check available functions based on the device model and iOS version. The current 4uKey technical specifications list support for iPhone models ranging from earlier generations through the iPhone 18 series, as well as supported iPad and iPod models. For those who need to verify whether their specific device is covered, the company maintains a supported device list that is updated alongside new releases.
The update also expands 4uKey's support for Activation Lock on compatible devices running earlier and newer supported iOS versions. According to Tenorshare's current compatibility list, 4uKey supports Activation Lock removal on compatible devices running iOS 26.0–26.1. Supported models include iPhone 11 through iPhone 17 series devices, iPhone Air, and selected iPad models. For iOS 18.0–18.7.2, supported devices include iPhone SE (2nd and 3rd generation), iPhone XR, iPhone XS series, and iPhone 11 through iPhone 16 series, along with selected iPad models. Support varies by device and iOS version, so users should check the compatibility list before starting an Activation Lock-related process.
Users do not need to determine compatibility solely from their iPhone model. The latest version of 4uKey can check the connected device directly. Step 1. Download and launch 4uKey on a Windows PC or Mac. Step 2. Connect the iPhone or iPad to the computer with a USB cable. Step 3. Select the relevant unlocking or Activation Lock feature in 4uKey. Step 4. Follow the on-screen instructions to check whether the connected device and iOS version are supported. Tenorshare recommends checking the supported device list before purchasing or beginning an unlocking process, as available functions can vary by model and system version.
In addition to supported Activation Lock scenarios, 4uKey provides tools for several other common device lock situations, including screen passcodes, Apple ID, MDM restrictions, and Screen Time passcodes. The update is part of Tenorshare's continued effort to keep 4uKey compatible with newer iPhone generations and supported iOS releases.
