spotify - ad supported being made available for mobile

hi,
I was just wondering... what with the annoucement today that spotify will be allowing users of the free ad supported version to access spotify from mobile devices.... will this be also extended to Sonos... will I once again be able to log in with my free account and play ad supported music? The 10hr cap is also being scrapped.... I'd prefer to access the music via sonos, rather than use their desktop app.

Thanks,
John
