The local pubcasting station iPhone app, announced in January, has been okayed by Apple and is now available in its iTunes store, says the Nieman Journalism Lab. It’s a free download from PRX and WBUR in Boston. One cool feature: There’s also an alarm clock that will play WBUR to wake you up. That idea was suggested by a listener. Although this one is WBUR-centric, its developers hope other stations develop similar apps using its open-source license. Here’s more info from PRX.
