open the pull up menu the hold the app icon. it will then allow you to move it wherever you want. i accidentally deleted the google bar by dragging it to the menu. unfortunately, once i held the google bar, the menu turned to a trash can. im not sure if i want it back because i can just hit the search button and add more apps to a top 4th row.
So far i have a flaslite, puzzle game skymap, barcode scanner, FML, droidtracker, cardio trainer, handy cards, my coupons, scoreboard, pandora, The Office sounds, voice recorder, irish slang terms, and sticky memo (which i have yet to figure out how to work). All free!
