An article in the current IEEE Communications Magazine authored
by a senior engineer at LG Telecom and a VP at LG Electronics,
makes an interesting comment.
It seems that the Korean market has shown that providing higher
bandwidth to the user is no guarantee of success for multimedia
to cell phones. Streaming media, MP3 downloads, and VOD do not
seem enough to justify the added cost. For this reason, the
article points out that migration to the EV-DV update of
cdma2000 makes good sense.
In the previous DO update, cdma2000 provided high bandwith data
only on a given frequency band, and the voice service was
available on a different frequency. In the data-voice evolution
(EV-DV), a single 3G frequency band is used for both services,
which increases the amount of voice channels that can be
supported. Voice still being the money maker.

This doesn't say whether a free multimedia to cell phone service
would succeed, though.
