Rate my Russian Roulette iPhone App
spaghetti: Looks great.  Seems snappy and responsive.  Good sounds.  Personally I like to see elements of humor in iPhone apps.  So perhaps you could add some sounds for the pull trigger "nothing" and pull trigger "shoot" cases.  For example when someone pulls the trigger and nothing happens you could randomly play a "Whew!" or "Well Kiss My Grits" sounds.  Then for the "shoot" case play a nastier sound.  Also some gun smoke might be nice.
