Artificial Life Inc. created Vivienne Rose everybody's virtual girl friend reachable on 3G phones.

Vivienne is a virtual persona created from voice synthesis, streaming video and text messages. She lives on a server and is able to converse about 35,000 topics. Not sure how important that is to the target group. A telling point is that the number one question answered in the FAQ on the V-Girl site is:
"Can I have sex (or Cyber sex) with the V-girl?"
Apparently she is a talker.

Vivienne is not online yet. Technical issues and cultural adaptions delayed the launch. Currently she will start to date in April in Signapure and Malaysia.
