After an earlier stumble, Vodafone's Nexus S users can once again get their hands on an over-the-air update to Android 4.1.1 Jelly Bean starting right now.
Jelly Bean started rolling out to Nexus S users almost a month ago. It was live for a few hours before Vodafone stepped in to halt the roll-out after issues emerged surrounding the ability (or lack thereof post-update) to make emergency calls.
Now, after some tinkering, the update is once again available for download. [Vodafone Blog]
