I have already highlighted the problem with this phones email App not being able to remember emails which already downloaded via IMAP resulting in deleted mails being re-downloaded every time phone syncs with my server. I now have a further issue as seems there is no way to bulk delete emails. Either deleting 'all' emails prior certain date. Or making a selection of multiple emails for deletion. Its really a shame as this could be a great business phone for users like myself dealing in large numbers of mail. Unfortunately seems SONY have a lot of work to do to catch up with the emails handling of phones like the Blackberry range. Spoils for me an otherwise perfect device.
