The Absolute Radio Player App for BlackBerry combines both FM and IP technologies to offer an "even more robust and consistent audio stream".
This involves the app automatically selecting the best technology to offer the optimum signal, either FM transmissions or streams over mobile data or WiFi.
BlackBerry users can access the 'Chat with DJ' function, allowing them to interact directly with the DJ in the Absolute Radio Golden Square studios, as well as other app users also streaming the station.
The BBM service is also now integrated directly into the app to offer social options to send, share and listen with friends and other users.
"Absolute Radio continues to redefine radio and our ambition to grow the Absolute Radio brand has been clear with our strong mobile strategy," said Absolute Radio's technology director, Paul Brown.
"The integrated BBM functionality of this app offers users a unique and highly interactive way to engage with both the station and fellow listeners, and we're delighted to have partnered with BlackBerry to bring such an innovative app to our audience base."
Gregor Park, the head of applications marketing UK at BlackBerry maker Research In Motion, added: "The ability for customers to connect, share and listen to radio with their BBM friends turns mobile radio from an individual experience into a truly social activity, which drives further engagement with the station's shows and greater interaction between the listeners themselves."
The Absolute Radio app, which replaces the previous version for BlackBerry, is available for download now from BlackBerry App World.
