Threaded SMS for E71

"The Conversation is an add-on application that allows you to follow your communication with contacts as streams of conversations, which it organizes, based on individual contacts. The application also makes it very easy to reply to received messages and continue an ongoing conversation with the contact.

After installation, the application will appear in your device as a new tab in your Contacts application. You can also set the application to be a short-cut key (e.g., left-soft-key or right-soft-key) or standby application icon in the Settings menu option in your terminal."

Personally, I do not feel that the application is well integrated. But for those interested, here is the full application file.
