The floodgates seem be open, folks - the Jelly Bean updates for the Galaxy S III are now rolling out all over Europe. Last month, Samsung shared Android 4.1.1 with Polish users, took a break to fix some bugs, and restarted the process two days ago in Sweden. As of today, the list of countries has expanded quite a bit - France, Spain, Romania, and Austria. All signs point to a much wider rollout, and I wouldn't be surprised if even more territories and carriers show up within the next 48 hours.
