The Department of Energy's Energy Information Administration is offering free wireless weekly diesel price reports by cell phone e-mail or through a Personal Digital Assistant (PDA), such as Palm Pilot.

A message containing the updated prices will be sent to registered cell phone/PDA e-mail addresses by about 5 pm EST every Monday. If Monday is a regularly scheduled government holiday, the prices will be sent Tuesday at about the same time.

The Energy Department says each individuals cell phone capabilities may affect the format for displaying the data. Anyone interested in signing up for the wireless update service should visit http://tonto.eia.doe.gov/scripts/lyris.pl?join=diesel-wireless.
