I can guess the replies. I am new to the Galaxy S and Android. I was looking for the live wallpaper that I had initially on the phone but coud not locate it on the phone itself, i therefore went to the Samsung Apps icon and was greeted by "Samsung Apps Update available, update?". I have over the past few months had some bad moments on my PC's when upgrading and feel very pensive about clicking onto the upgrade. What is the upgrade for? Am I completely paranoid about updating? I know "the feller is a nut"......
