I'm not sure if this has already been mentioned.
But when you press the menu button while on the first menu, it takes you to search. This is just another way of getting there, instead of swiping to the left!
If you change double-click for the home button under your general settings to search and turn off ipod control you can get the search page from within any app as well as any springboard page.
If you don't launch any app or documents under search page and just close the keyboard it takes you back to the Springboard first page instead of back to the app that you were in. This means that the Spotlight is not a separate app and is part of the Springboard app.
