I hate that. When I was buying my iPhone at Best Buy, the girl who sold me my iPhone went through all the setup too. I was kind of annoyed because it was my new iPhone, and I feel like that's part of the experience.
If you do want to access the setup assistant, you would have to erase all content and setup as new.
Settings>General>Reset>Erase All Content and Settings.
But the setup from the setup assistant just has the information in Settings if you don't want to go through the full setup again.
