KMobileTools is an OpenSource project (GPL2 license) that aims to be a complete management system for mobile phones.
It's written in C++ using Qt and KDE libraries. It's using KParts technology, so it can be embedd in every application (like in Kontact), it can read and write KDE AddressBook, full import/export, read and write SMS, export them in KMail, and much more. All this depending on your phone capabilities, of course.
CALL FOR DEVELOPERS: please check on the kde-apps project page how you can help and contribute. Without a new developer team KMobileTools won't be finished in near future. HELP IS REQUIRED!
