No official cheat menu exists in Spider-Man 3 Collector's Edition for PS3. The "Collector's Edition" only added a bonus disc (making-of, webisodes, art) and packaging—no gameplay differences from standard edition.
Note: If you want a Spider-Man game with built-in cheats, Spider-Man 2 (2004) on PS2/GameCube/Xbox has a well-known cheat menu (enter codes at main menu).
