Hi folks, I have a Google Nexus S & I am quite happy with its performance as of now. Recently I've recieved an update from Android to upgrade my current version "Gingerbread 2.3.4" to "Gingerbread 2.3.6". I am more than eager to do it, but also I am afraid that I may lose my contacts, my Stored Photos & Videos and also my Apps that I have Downloaded from Android Market. As some of these apps are paid. Please resolve my contention and tell me whether I should go ahead with this and it will not harm me in anyways?
