I was just downloading the latest Java update from Sun over AT&T
Wireless HSDPA with my V3xx, and the sustained download speed as
measured by Firefox was 133 KBytes/sec*, which compares pretty well to
wired consumer broadband. See <http://i28.tinypic.com/2qw1nx0.png>
What's not to like?

* Over 1 Mbps net transfer speed, or nearly 1.3 Mbps raw speed
