We have just released Python-GPSbt and Python-abook, providing access to GPS and address book data. Both modules are available through Application Manager as separate packages. We will collect all user opinions about them and possibly these packages will be included as part of a new PyMaemo release.
GeoClue bindings will be provided as soon as it gets a bit more mature. In fact its possible to access its API using D-Bus calls.
Finally, thanks to Eduardo Rocha for suggestions on how to improve py-gpsbt.
