The E72 Gmail app does not allow you to
- Send attachments via Gmail
- Download attachments (you can only view attachments in text only)
- Delete emails relatively easily
- Auto-complete email addresses that you are typing in
Since Gmail now supports IMAP, Nokia Messaging connects to Gmail using IMAP. This means that when you delete emails on the Nokia Messaging inbox for your gmail account, you will effectively be deleting it from your Gmail account. I also understand that connecting via IMAP means that you can now get emails into your inbox as soon as they come through to Gmail without delay
Another thing you can now do with the Nokia Messaging interface for Gmail is you can auto-complete your email addresses as you compose your email. Auto-complete does not come with the Gmail application that is available for the Nokia E72 which means a lot of fussing around with copy and paste.
