It's slightly different to the PC platform in that the assumption, rightly or wrongly, is that customers don't generally install custom operating systems on their phones and tablets, and indeed I think there would be some reticence on behalf of the phone companies to allow that from both support and system security perspectives, so if the hybrid phone came to fruition, the version of Ubuntu on the phone at least would theoretically be only upgradable through maker and telco paths.
