As a whole bunch of you have been submitting, apparently Apple yanked Grooveshark's iPhone app after receiving a complaint from Universal Music, one of the record labels who has sued Grooveshark, and is claiming that it has not properly licensed the music. Grooveshark has argued for years that what it's doing is legal, but multiple record labels have disagreed. Still, Apple wants to keep the major record labels happy, so bye-bye Grooveshark. Perhaps they should explore creating a web app and putting it on something like the OpenAppMkt, since that's outside of Apple's control...
