26 years in the making, worldwide mobile subscriptions have reached 3.3 billion according to research firm Informa Telecoms and Media. As of, oh, right now, the US Census Bureau puts the global population at 6,634,545,153. This doesn't mean that half the world has a cell phone, since 59 countries have mobile penetration of over 100 percent, meaning at least some people have more than one subscription. I--gadget yuppie that I am--have 17.
