The Samsung Galaxy S II, the still-popular older brother of the Samsung Galaxy S III, has finally graduated to Android 4.0. Although some AT&T customers reported having access to the Ice Cream Sandwich updates on their S2 devices last week, Samsung said that the upgrades were still being tested and thus pulled them off the Samsung Kies app. Users are now reporting that the update is back up again and is running smoothly. T-Mobile Galaxy S II users, of course, got their ICS update on June 12, so AT&T has been a wee bit behind in getting things up to speed. And for what it’s worth, XDA Developers forum members have posted some sweet pics of what Ice Cream Sandwich looks like on the Galaxy S II on AT&T.
