Nokia made a beta program called Conversations available for download today that enables threaded SMS similar to that seen on the iPhone or Palm Treos. The application groups conversations by contact and strings them together so they can be sorted easily in the messaging application. It also adds a way for users to reply to SMS messages from the application and maintain on-going conversations easily. Two separate applications must be downloaded in order for Conversations to work, and Nokia recommends that your device is updated to the latest firmware. It will work on most S60 3rd Edition E Series and N Series devices.
