Well, if you are one of those who did wait, you will be glad to know that the Android 4.0.4 update is now rolling out over the air for the Galaxy S II. The update brings some performance updates and bug fixes and is only available for the international model for now.
If you have one of these devices then you should check to see if the update is available for download. You will need to connect your phone to Kies to download the update.
