I just released version 0.24 of Wammu. This release brings improvements in device searching, support for notification on incoming call (you need python-dbus for this) and various minor GUI improvements. Full list of changes:

• Notifies user about incoming calls using D-Bus.
• Remember default type of created entry (eg. phone/SIM memory).
• Newly created entries contain some reasonable fields by default.
• Fixed validation of editor fields.
• Improvements in guided wizard to make it easier to use.
• Clever searching over Bluetooth based on manufacturer.
• Searching can be really limited to some connection types.

There is still no binary for Windows. I don't have time and environment for maintaining them. Volunteers are welcome!
