Did you think that the Galaxy S III was the only one getting all of Samsung's Jelly Bean attention? Not so! As it turns out, the company is also working on Android 4.1 for older phones, including but not limited to the...*deep breath*...Samsung Galaxy S II Epic 4G Touch. A build has leaked out over on XDA of 4.1.1 in all its TouchWiz-ified glory that's ready for the flashing looking at, if you're feeling adventurous bored.
Of course, keep in mind that this is an early build of unreleased software, so make your backups and be prepared for some problems here and there.
