Ghosts Clan

Does anyone know how to leave A Ghosts Clan w/o the iOS app?

Multiplayer -> Online Play -> Barracks -> Clan Details?

EDIT:

Alternatively you can:

Multiplayer -> F1 (Friends List) -> Right arrow till you see your clan - > click yourname -> Leave Clan

Thanks! Do you also know how to do it on the xbox 360?

Same method as the alternative posted above but with the respective controls for Xbox...
