Last Thursday Verizon Airfone notified customers that it will continue to provide MagnaStar users with air-to-ground communications “through at least December 31, 2007.” This action reverses a Verizon announcement this summer that it would exit the air-to-ground phone business in December, leaving some 4,100 Teledyne Control MagnaStar operators that use the Airfone network weighing options for other service providers. Thursday’s letter also said, “We will update you as soon as more information is available.” On its Web site, Verizon says it is accepting new service agreements “with the understanding that service will be available through at least December 31, 2007.” During a recent FCC auction, AirCell bought the spectrum that includes Airfone’s 800-MHz operating frequency. JetBlue Airways’ LiveTV also won part of the available spectrum up for bid. Under terms of the sale, Airfone could operate for two more years using a portion of the AirCell spectrum, then two more on LiveTV’s spectrum.
