Griffin Technology today released iTrip Software 2.0, an update to its software that installs all available US frequencies on an iPod or iPod mini. Users can then change the broadcast frequency of their iTrip or iTrip mini directly from their iPod. This new software improves the installation experience and adds 87.7 as an available frequency to US iTrip owners. The new iTrip Software Version 2 is available immediately as a free download.
