I was able to update my iPad to iOS 4.2 GM a week ago. I have never installed an iOS early release or beta.. so im not sure what the next step is. Once iOS 4.2 is officially released, will iTunes automatically ask me to update my iPad the way it always does on a firmware update? Or will it not recognize that I need a software update because it already sees I have a version of 4.2? I hope my question makes sense. Thanks.
