Can you change your character in Skyrim

if you already made your character in the beginning of the game you cannot change it unless you have the PC game you can type in a cheat code which will reset his skills but you can always change how he or she looks if on ps3 or xbox 360 i don't believe you can with out starting a new game i had it for the PC but don't play it any more cause i like there previous game oblivion better
