The application is available for both iPhones and iPads with a graphical user interface which works very similar to the UFED Touch and UFED4PC device. It allows you to search for vendors and mobile device names and even find out if Cellebrite can acquire the data even if the device is locked.
If you already have access to the Cellebrite portal, you will need to use your same credentials to access and use the application. This is a nice and free tool to have for anyone involved in digital evidence investigations!
Here is a direct link to the iTunes store to get the app!
