We reported earlier that signs at the Moscone West convention centre gave a clear indication that Apple is going to announce the next version of its iOS operating system – iOS 7and that may very well be the star attraction of Tim Cook’s keynote. According to a separate report on WSJ the iOS 7 will feature Jon Ive-inspired ‘plain solid backgrounds and more white spaces.’

The report claims that Apple’s new streaming radio service – allegedly dubbed to be iRadio, will also be launched at WWDC. The service will have both text as well as audio ads and will have “Buy” buttons alongside the track in progress. However the report doesn’t indicate presence of any sort of paid tiers like the ones offered by Spotify or Pandora.

Apple had been working on iRadio since over a year now but, with Google releasing its Google Play Music All Access, Cupertino put its streaming service plans into overdrive claims the new report.

It’s a matter of hours now before we come to know what’s in store at the WWDC 2013.
