I'm planning to upgrade my Galaxy S2's OS from android 2.3 to 4.0. This is an official upgrade from Samsung.
It sounds like it's an easy process. Just download the Kies program from Samsung and follow the instructions. But as I've never done it before on an android, would I still have all my apps and data? Or will I have to redownload them all again?
Is there a chance that something could go wrong?
