When I send email from my phone, the wrong name shows up in the "From" field
I have Mail set up to use my Gmail account, which uses the correct name, and it's not an Apple Mail problem -- I tested by sending an email to myself from Apple Mail on my laptop. I think what's going on is that my mother (who bought the phone for me as a gift) registered it under the wrong name -- my name is Kay, but she insists on calling me Katie. Does anybody know how I can confirm this and change it to the correct name?
