iPhone 4 Mail Usage Size Problem My email on iPhone 4 consumed 8 GB from usage.  I deleted all mail and the account and there's still 8 GB consumed.  I use STMP mail.  What else do I need to do?.
Did you restart the phone after you deleted the emails? If that doesn't work, try removing that particular email account, rebooting the phone and then re-adding it via
Settings App > Mail, Contacts &amp; Calendar
