This application is a really easy way to export your contacts to your SD card, and to send them by email.
If you prefer, the CSV file is automatically saved at your SD card root, with the name "contacts.csv".
It not only exports names and phone numbers but also all informations registered (work, city, street, ...).
You can do the same for all your SMS too, and you can send it by email or get it at your SD card root, with the name "sms.csv".
Try it, you will appreciate !
