I just uploaded the latest binaries (JAR and JAD) of Mobile Task Manager to Google Code download page. The previous version (v1.2) was already downloaded over 1700 times in less then a month so there seems to be a need for a good GTD / Task Manager application :)
This version fixes the issues with the export and import. Now you can export data to CSV file correctly and you can import that file either to root folder or to the folder that is currently selected.
This version also improves the startup time significantly. Application is ready to use in about three seconds after the launch on my Nokia E71.
Have fun while Getting Things Done with the Mobile Task Manager! :)
