As the tiny version number change (2.3.3 to 2.3.4) suggests, this is not the most major of updates, but there is still plenty to look forward to. For one, the Galaxy S II will finally get Google Talk video calls enabled. Early adopters also report an improvement in battery life. The new modem drivers are also said to bring notably better reception for some.
If you do not feel like waiting for Samsung to seed this update officially, you can head this way to download the leaked ROM and follow the instructions in this PDF to install it.
However, you should bear in mind that will, most probably, void your warranty. Also installing the ROM might damage your device, so you should only proceed if you know what your are doing.
