How to change the default signature
I don't like their default advertisement signature that says "sent from my iPad".
Here is how to change it to your name.
How to Change a Mail Signature
Each time you send out an email using the Mail app, it adds a signature "Sent from my iPad". If you dislike this signature, clear or replace it with your own.
Open Settings, select "Mail, Contacts, Calendars", and tap "Signature" on the right panel.
Clear the signature "Sent from my iPad", or replace it with your signature or name in the accounts you choose.
Tab the "Mail, Contacts..." button when done.
