Can't wait houres in line so don't have a 3G yet. However there is one thing that concerns me. Lots of time while I'm eating or at my desk I will use one hand while it is sitting flat. It looks like this will not be possible with the 3G since it may rock and slide. Have not read about this being a problem. Am I the only one who sometime uses the iPhone with one hand with it's sitting on a flat surface? Does anyone else miss the flat back for this purpose?
