how i change my email of reset answers security info ?

Go to http://appleid.apple.com and click 'Manage your Apple ID'. Log in.

In the left sidebar click 'Password and Security'. Answer the two security questions you will be asked.

You will then enter a page where you can change the questions and the 'Rescue email address'.

Then you can get reset answers sent to the rescue address currently on file. If you can't access that you will have to contact Support. Go to https://expresslane.apple.com ; select 'All Products and Services' in the first column, 'More Products and Services' in the second column, then 'Apple ID' in the third column. In the next page select 'Other Apple ID Topics' in the first column then 'Lost or forgotten Apple ID password' and click 'Continue'. You will be offered options to contact Apple.
