Q: since the upgrade, my Icloud account is picking up a former account name-e mail address  I no longer have that address and cannot seem to be able to edit it to change it   the password is always wrong, no matter what i try

since the upgrade, my I phone I cloud account is picking up my former e mail address/account name and I cannot access it because it keeps denying the passwords I try   I no longer have that e mail address either    I can access I cloud and I tunes on my laptop with the correct account name/password,but not my phone     the i tunes account works fine on the phone--correct name--just not  i cloud       i tried changing it from my computer back to the old address then changing it to the new address and verifying by e mail but nothing happened
