Rename mail account? I hope this is not too obvious, but I would like to know if this is possible.  I made an email account without renaming it.  So it has the boring name Exchange.  How can I rename this email account on my iPad without deleting and re adding it?  I would rather not type all that info in again.
Go to Settings > Mail, Contacts, Calendars > Tap your Exchange account (for you, it will likely say Exchange) > Tap on your exchange email address (i.e. daniel@example.com) > scroll down to Description (past Username and Password), then enter the new name in there.
