I think this was in another thread a few months back, has something new changed this since Jan 1?

Updates 4/2005: Verizon Wireless and U.S. Cellular Corp. have always been opposed to the proposed cell phone directory, and initial partners Sprint Corp. and Alltel Corp. have since pulled away from the project due to concerns about bad publicity and possible new government regulations. So even if the cell phone directory database was compiled as planned, at least 45% of U.S. cell phone numbers wouldn't be included.
In April 2005, USA Today reported that registrations for the national do-not-call list for the week ending April 2 were about double the normal level, and registrations for the following week reached a peak five times higher than average. The newspaper also reiterated what we stated above:
. . . the anxiety is unfounded. First, it's illegal to make sales pitches to wireless phones by using automatic dialers — which is how the vast majority of telemarketing calls are placed. (One reason is that cellular users must pay for incoming calls.)
Also, most of the big wireless carriers have chosen either not to take part in the directory or to put off any plans to do so in light of consumer fears. They say any directory would include only those customers who agreed to participate and that the numbers would not be shared with telemarketers or anyone else. Congress has considered a bill to codify such rules.
