INQ's CEO Frank Meehan told Business Week that the company plans to make it easy for owners to use Spotify on their mobile phone.
The app, which is only available to those with a Spotify Premium account, which costs £10 per month, lets users search and play tracks from Spotify's catalogue over a phone's Wi-Fi or 3G connection.
Meehan didn't reveal any more details about the handsets. He also declined to comment on rumours that INQ is working with social network Facebook on developing a number of mobile phones.
Last month, Bloomberg claimed the handsets will initially be launched in Europe in the first half of 2011, and then be made available in the US.
