KDE-based application that allows mobile phones to be controlled with your PC. GPL

KMobileTools 0.5.0-beta3 handles full SMS control, dialing calls, phonebook, and phone status monitoring. It's also integrated with the KDE environment, so it can be embedded in Kontact and can import to or export from KAddressBook. It's developed with a Motorola C350 mobile phone, but also has good support for all AT compliant devices.
