The main features introduced with this version are auto loading of phone call & SMS log, calculating charge for past calls & SMS, support of charging units shared by both call minutes and SMS, and new special rates format. Check its change history for details, and the FAQ for the new special rates format.
The support of calculating charges for the past should be helpful for smartphone edition, as it doesn't need the monitor module running all the time. But again, please contact me for the smartphone edition. It's still in the test stage.
