access default email address
<p>I am using the MFMailComposeViewController in 3.0 to send an email with attachment etc. inside my app.  I would like the "To:" address to be defaulted to the default account/address on the device.  How can I access this address to place it into a string for the setToRecipients?</p>

<p>Essentially, I'm going to let the user send an email to themselves (as the default "To") with an attachment inside the app.</p>
