How to Read E-Mail Messages on Your iPhone
One of the reasons you probably bought an iPhone in the first place is because you wanted to use it to check your e-mail. Once you've set up your e-mail account, all you have to do is tap the Mail icon on the Home screen. The Accounts list appears, and the Inbox in that list displays the number of unread messages in a blue oval to the right of its name.
If you have more than one e-mail account, you may have to tap the Accounts button in the upper-left corner and then choose the appropriate e-mail account before you see the Inbox with the unread messages.

View the buttons for managing your e-mail.
To see the list of unread messages, tap Inbox in the list of mailboxes and then tap a message to read it. When a message is on the screen, buttons for managing incoming messages appear below it, as shown here.
