http://askubuntu.com – This question already has an answer here: When is the expected stable release date of Ubuntu Phone and Ubuntu Tablet? 4 answers I want to use Ubuntu Phone OS on my phone, but I don't know whether it's ready to use for general public. Is there a release version already? If not, when will it be? Ubuntu Phone OS is great. I hope Canonical won't give it up. (HowTos)
