Orange is to become the first UK network to launch mobile interactive radio across the UK. The service, will be the “Woolworth's hit40uk,” and be broadcast simultaneously on Orange mobile phones and 113 radio stations across the country from 4-7pm every Sunday.

By using a unique application created by Somethin' Else, Orange users can listen to and interact with the charts as they happen, using everything from SMS to video.

The service, which will launch today at 4pm will allow listeners can now tune into their local radio station and follow at the same time on their mobile handsets each Sunday afternoon. As the chart counts down to number one, Orange customers can follow the chart, download any of the ringtones from the top 40 and find out more about the artists and bands that they are listening to.
