No, this is not the Ice Cream Sandwich update we have been waiting for. Instead, it is a 70 MB update bringing a few new features. The first update is to the keyboard. Now there is a fifth row for numbers and an option to make the keyboard smaller for one handed typing. Next is some minor visual changes to the lockscreen. It should also be slightly easier to unlock after the update. Samsung also added a new widget to toggle the LED light. The last of the notable changes is an option to change the brightness of the screen while using the browser independently from the brightness of the screen normally.
Have you gotten the update yet?
