E-mail was the first killer application for the Internet-now messaging is coming to cellphones. How does a software application go from zero to 100 million users in a couple of years? One way is to be built into Windows. Another is for the world\´s largest cellphone manufacturers to make it a standard. That has not happened yet, but it\´s about to. Three titans of the mobile world, Nokia, Motorola, and Ericsson, are behind a developing standard for instant messaging (IM) between cellphones. Called Wireless Village, it was approved in February as Draft 1.0 by a consortium that includes more than 150 equipment manufacturers, and could be implemented in new cellphones by early fall.
