If the novel '1984' by George Orwell is any indication, we're there dude. Now, you can check everywhere your iphone has been since the 4.x update by downloading a program on the computer where you back up your iphone. Once installed, it searches for your backup file and more specifically, the file that tracks your iphone movements and displays them prominently on a map. When I first heard about this, I was skeptical, but after downloading the program and running it, I saw my trip to Chicago and numerous visits to the New Orleans and Lake Charles areas. Why this data is being kept is still a mystery, but just be aware it's being kept on your iphone and your backed up files. You can download the program here
