If you go to www.yahoo.com there should be a little icon displaying your picture (or a default thumbnail) and a "Hi {your name}" beside it if you're using the new homepage layout. If you hover your mouse over that message a drop down menu will appear. There will be an option to edit your account on that menu - if you click that you'll be able to edit your account details.

jcleblancI received an up date that my Yahoo account had added a phone number. Well guess what it is incorrect. Where do I go to change the profile?
