iOS Kiosk App - In-App Email - Clear past / autocomplete email addresses

I am using the iOS MFMailComposeView method of sending emails - its all working fine, except that as a Kiosk app, I don't want each new user to see the auto complete list of previous email addresses that this app / iPad has used.

Is there a programmatical way to clear that cache after each email has been sent?

I can't see from the Dev docs, but I'm sure I'm not the only one that's butted up against this problem.

Thanks

I've had confirmation from Apple that there is no way to do this at all without a complete reset/wipe of the iPad between 'events'.

I logged Bug ID# 10328043 and in the reply was told that they already knew about this 'problem' as the original bug ID # is 5389647

If anyone else would like to help raise this as an issue requiring a sooner rather than never solution, please bug it and reference the two above ID's.

Thanks
