The Ubuntu Touch Developer Preview has been released. This includes the source code and images for both the phone and tablet interfaces and are aimed at developers so it's not something you should install for actual every day usage. For now you'll find that some features are missing, like playing music, no mobile data connection, PIN/PUK support, etc., there are bugs and so on.
The images support the following devices: Galaxy Nexus, Nexus 4, 7 and 10.
To flash the Ubuntu Touch Developer Preview on your device, you'll need to use a PPA which supports Ubuntu Precise, Quantal and Raring. For complete instructions, see https://wiki.ubuntu.com/Touch/Install.
After flasing, you'll get the shell and core applications, working connection to GSM network, working phone calls and SMS, networking and Wifi and a functional camera. Also, you'll be able to use adb, just like on Android.
Along with the Ubuntu Touch Developer Preview, developers can also download the Ubuntu SDK, currently in alpha, which lets you deploy and execute the apps as they create them, from the IDE.
