Unlike most smartphones, the end-user is able to gain root access by installing an application, such as the "rootsh", and then issuing the appropriate command in the terminal in Maemo 5. The device does not need to be unlocked or "jailbroken" in order to install an unsupported application. The UK cellular operator Vodafone has its own branded, somewhat more restricted version of the Maemo 5 operating system. Users can flash (change) to the global variant of the operating system if they wish.
