switch cell service, keep number   (opinion)

short version: on Nov. 24, 2003, if you switch cell service, you can most likely keep the same phone number

long(er) version: i keep hearing people ask when the date is that cell service providers have to let you keep your phone number if you switch service, so i finally asked the internet, and Wired has an article from the end of December 2002 about the whole issue.
