BERWYN, PA and SANTA CRUZ, CA (March 31, 2008) - BlackBerry® smartphone users can now keep track of what is playing on their favorite radio stations throughout the U.S. in real time, thanks to a unique new entertainment application called Radio Companion™.

This free, downloadable application - which operates on such popular BlackBerry models as Pearl, Curve and the 8800 series from Research In Motion (RIM) (NASDAQ: RIMM; TSX: RIM) - was developed by mobile application developer, Nobex Technologies, and is powered by Mediaguide, a top provider of airplay data drawn from terrestrial and Internet radio, as well as major peer-to-peer networks.

Through its proprietary fingerprinting technology and network of remote monitoring stations, Mediaguide currently tracks the real-time airplay of more than 2,700 terrestrial radio stations in every state in the U.S. This allows Radio Companion users to see what is playing right now on any of their favorite radio stations with just a few quick clicks on their BlackBerry. They can then select the music track to have its details sent instantly to their email account, with a direct link to click-through and purchase the song online.

"The BlackBerry platform is ideal for this kind of entertainment offering," said Steve Lubin, CEO of Mediaguide. "It is the mobile device of choice for millions of Americans and has become a key access point for all types of information and services. Bringing music-oriented applications into the BlackBerry ecosystem is a natural evolution in how consumers are using this device."

Radio Companion is fast to download and set up. Users simply point their BlackBerry browser to www.nobexrc.com and click the link to download. During the brief set-up process, users are prompted to select their favorite radio stations by scrolling through an alphabetical list of cities and then picking their stations. This list includes more than 2,700 stations from all music formats and genres throughout the country.

Once set-up is complete, users click on a station name to see what is currently playing. Radio Companion displays the song title and artist, as well as a thumbnail graphic of the album cover or artist photo. They can also scroll backwards to view previous songs and artists on the station's playlist.

"When you're tuned in live to a station but don't know the name of the specific song that's playing, Radio Companion can tell you in an instant," said Gadi Mazor, CEO of Nobex. "Some people listen to a particular station to get introduced to new music. For them, Radio Companion is a great tool for scrolling recent playlists to discover tracks they may want to check out."

Lubin added that Radio Companion is also terrific for people who have a strong personal connection to a radio station from their old home town, such as their college station. "They can follow what's on the air, even though they no longer live in the area," said Lubin.

Radio Companion does not yet stream audio from radio stations directly to BlackBerry smartphones. Nobex and Mediaguide anticipate adding this feature in late summer of 2008.
