An anonymous reader tells us about a BusinessWeek story claiming that in a few years most wireless plans will be unlimited
. And pretty costly: unlimited cell calling, SMS, and data for on the order of $115 - $150 a month. Sprint is conducting a trial of such an offering in San Francisco, with the intent of rolling it out nationwide, and other carriers are said to be sure to follow suit. An interesting claim in the article is that in 5 years time, 40% of the US population will be untethered from landlines and using their cell numbers exclusively (vs. 15% now).
