when setting up my iCloud account i mistakenly misspelled my login and i would like to change this

Hi ken,

Thanks for using Apple Support Communities. I understand that when setting up your iCloud account you accidentally misspelled the login info. The iCloud account username is an Apple ID and there is a terrific article that can show you how to edit that Apple ID and correct it. Be sure to make sure you follow the top section, Before you change your Apple ID, before proceeding to the steps to change it.
