Samsung has released the source code for the Galaxy S II, opening the door for developers to craft more complex apps and modify Samsung's customized Android 2.3.3 build. The GT-I9100 open-source repo will allow for ROMs that further overclock the GSII's 1.2GHz processor, among other things.
Samsung has been criticized in the past for its attitude toward updates for its existing Android phones While this isn't necessarily a sign that the firm is upping its game overall, it's a welcome release.
You'll need to be a developer to make the most of the download - which you can find here - but users should likely expect the fruits of dev's efforts in the not too distant future. More on the Galaxy S II in our full review.
