Developer preview for Ubuntu Phone due this week - Update
Canonical is planning to release the "Touch Developer Preview of Ubuntu for phones" on Thursday 21 February. This release will allow developers to put images of the phone-optimised Ubuntu onto the Galaxy Nexus and Nexus 4 smartphones. The images are billed as "early previews" to allow developers to create applications for the phone operating system and, rather than being a snapshot of development, will be supplemented by daily updates.
