At the moment I have 700 plus emails in the Trash on my iPad2. Is it possible to mass-delete them without having to click every box? At the moment I delete them from my Inbox, they go to the Trash and I have to go through the process again.

You can easily empty the Trash in one go, just open Mail, select your account then the Trash folder in the Accounts section. Tap the Edit button at the top and press Delete All. To save you the bother of doing it again go to Settings on the home screen, select Mail Contacts Calendars then your account and touch the Advanced button. Under Deleted Messages select Remove and choose an appropriate timeframe for automatic deletion (i.e. One Day, One Week or One Month).
