Recently we (e-office mobile) introduced Mobile Data Alerter. This application helps you monitoring your data usage and so helps you save some money. People who travel often but not often enough to have an international data-plan in place love this tool. We've listened to the feedback of our early bird testers and also decided to put some extra love and care in the user interface. We strongly recommend everyone to upgrade to the current version, available at http://mda.e-office.com
