Gmail for Android now offers more reliable support for IMAP accounts. (youmobile.org)
Email - From the BlackBerry Hub, the user can now: File a sent email message in a folder that is created by the user in the email client on a computer, Set the sync interval for IMAP email accounts, to control how frequently email messages are synchronized with the user's BlackBerry device, Automatically save a draft email by leaving the BlackBerry Hub, Download and save all the attachments in an email at the same time, Delete the original email text when replying to an email (crackberry.com)
I prefer this feature to dumping content only into the cloud (same reason I use IMAP e-mail with a local backup, not just Web mail) because having offline access can be important for lots of reasons. (slaw.ca)
