Seems like a nice app in lieu with contact apps of phones like 5800!

Downloaded from the link you provided but there seems to be a missing dependency with libqtm-contacts. Unable to install if this is not resolved.

Probably I'll lookup in this forum and see if someone has faced a similar pbm but thought of alerting you as well in case you yourself are able to resolve this!

Edit: libqtm-contacts dependency resolved with apt-get install
