As promised, Samsung has finally made Android 4.0 available to Galaxy S II users in South Korea via Kies. The company also announced the first details of European availablity — Poland, Sweden, and Hungary will also be getting the update today, with more countries on the way. It looks like the UK could be one of the next up, as a tweet from Brendan Arndt of UK carrier Three has revealed that their final build of Ice Cream Sandwich is currently undergoing internal testing. Samsung has also announced plans to upgrade older devices to Android 2.3 Gingerbread, including the Galaxy Tab 7.0, Galaxy S, Galaxy W, and some regional variants like the Galaxy M Style and Galaxy S Hoppin.

Update: The European ROM is now available to download from xda-developers and MoDaCo.

Update 2: Samsung has officially confirmed that the UK rollout will begin next week, though the specific timing for each phone will be dependent on carriers completing their software approval processes.

Thanks, molloLFC!
