Heh, did you ever try going left of the leftmost home screen? I was extremely annoyed that it wouldn't revolve back to the rightmost one -- utterly unintuitive, if you ask me. Same thing if you reach the end, it doesn't go back to the beginning as one would expect. The fact that the screen would move sort of halfway and then spring back confused me even more, since it made me assume that it can move but I am not swiping all the way, so I kept trying for a short while...

PS. You may want to consider putting a space after each punctuation mark.
