The past week my mailbox has been swamped with readers/viewers asking where I got my iPhone 4 background.   The short answer is, I have no idea.  It was sent to me well over a year ago, and had just been living in my pictures folder.  However, with iOS4, and the ability to change backgrounds, I though it would make a fun and unobtrusive wallpaper.  So, here it is, in all it's download glory, have at it.
