Hier die Antwort auf meine Anfrage bei TomTom:
".....Thanks for your mail.
Currently, we are investigating the options to release software like City Maps
and Route Planner for
SYMBIAN 7.0 based phones like Sony/Ericsson P800 and Nokia 7950
However, we can not give you any date when to expect a release.
Watch our website at http://www.tomtom.com to stay informed of new releases.
Regards,
TomTom Customer Services...."
