There are different approaches to establish open source technology in mobility technology.
- Android is a software platform and operating system for mobile devices, based on the Linux kernel, developed by Google and later the Open Handset Alliance.
- Maemo is an operating system for the Nokia Internet Tablet line of handheld computers. It is based on Debian GNU/Linux and draws much of its GUI, frameworks, and libraries from the GNOME project. It uses the Matchbox window manager, and the GTK-based Hildon as its GUI and application framework.
- Qt Extended, formerly known as Qtopia until September 30, 2008, is an application platform for Embedded Linux-based mobile computing devices such as personal digital assistants, mobile phones, and web pads. It is being developed by Qt Software, a subsidiary of Nokia.
- Openmoko is a project which encompasses two related sub-projects, with the combined aim of creating a family of open source mobile phones. The project was founded by FIC, a taiwanese microelectronics hardware manufacturer. The first sub-project is Openmoko Linux, a Linux based operating system designed for mobile phones, built using free software. The second sub-project is the development of hardware devices on which Openmoko Linux runs. Especially interesting: Unlike most other mobile phone platforms, these phones are designed to provide end users with the ability to modify the operating system and software stack.
