There are plenty of simpler phones (e.g. not a PDA, touch screen, read your e-mail thing) that can use cellular data to WEP browse, or to fetch things like ring tones. They use an IP on the network.The term is ill defined, but the general connotation is that they will be supplanting dumb phones. So say what you will,phones with IP addresses is likely to increase as a percentage of the installed base. The only thing offsetting that is the indication that the U.S. is saturating on total # of cell phones, which is what that article says.
Of course, my iPhone is currently showing an IP address in 10/8, and though my EVDO card shows a global address in 70.198/16, I can't ssh to it -- a TCP traceroute appears to be blocked at the border of Verizon Wireless' network. But hey, at least I can ping it. (Confirmed by tcpdump on my laptop: the pings are not being spoofed by a border router.) --Steve Bellovin, http://www.cs.columbia.edu/~smb
