CallHistoryExport is a small utility that allows you to export your phone's call log. Upon starting it exports all call records into one text file. When the export is complete it shows the final dialog with the number of call records written.
This export may be useful for statistics purposes, call analysis, etc. Anyway, it is not so difficult to think up why one may need to export calls (no matter completed or just dialled or dropped) very quickly without PC connectivity.
