How to enable JIT for iOS 17 using SideJITServer
SideJITServer is a command line utility designed to activate Just-In-Time (JIT) functionality for compatible applications operating on iOS 17 devices, seamlessly bridging Windows, Linux, and macOS within the shared WiFi network. Developed and continually refined by nythepegasus, a valued member of the SideStore team, this tool empowers users with enhanced performance capabilities for JIT iOS apps.
SideJITServer is a Python script designed to be executed within a Python environment on your desktop. As of its latest release, it mandates the following component versions: `pymobiledevice3>=4.2.3,<4.3.0`, `Flask==3.0.2`, and `zeroconf==0.132.2`. Attempting to use different versions of these components may result in errors when running SideJITServer. Therefore, it's crucial to adhere to these specified versions to ensure optimal functionality.
Installing SideJITServer
Step 1. Create a virtual environment named "venv" using Python to use an isolated environment for the Python project.
python3 -m venv venv
Step 2. Install SideJITServer following the pip3 installation command for the package.
pip3 install SideJITServer
Step 3. Install pymobiledevice3, the python3 implementation of various tools for iDevices. It's recommended to use the latest version of pymobiledevice3 <4.3.0.
python3 -m pip install -U pymobiledevice3
Step 4. Execute the launch command to see if SideJITServer is installed on your Desktop. Additionaly open the http://127.0.0.1:8080 in your browser to view if the device is paired.

Configuration
Step 1. Connect your iOS 17 device to your computer and execute the following command to pair it. Next, grab your iPhone and continue the next steps.
SideJITServer --pair
Step 2. On your iPhone's Home Screen, a 'Trust This Computer?' popup will appear. Tap on trust and provide your PIN to allow connection between the PC and iDevice.
Step 3. Run SideJITServer to start the server on your computer. It may require a sudo command. In this case, enter your password when prompted.

Step 4. Add this Shortcut required to detect and run apps in JIT mode.
Step 5. Tap on 'Set Up Shortcut' from your device's screen.
Step 6. Provide your device's UDID. It can be easily discovered by entering this IP http://127.0.0.1:8080 in your browser. Example UDID "00022010-001A5BC60CS9012X".
Step 7. Next, enter your server address. It will be displayed in the terminal app running SideJITServer. It's important to provide the full URL address including http and port.
http://192.168.0.241:8080
Enabling JIT for iOS 17 app
Step 1. Be sure that SideJITServer is running on your Desktop. If it's installed correctly you will see the paired device UDID in your browser. Open the Shortcuts app from your iOS 17 Home Screen and tap on the SideJIT previously added shortcut.
Step 2. Allow SideJIT to connect to "192.168.0.241".
Step 3. SideJIT will display a list of all installed apps on iOS 17 with support for JIT. Select the one you like to open in JIT mode.
Step 4. The application should open in JIT-enabled mode on iOS 17.
