Beverly Hills, Calif. - Mobile entertainment publisher Jamba on Friday announced the launch of "The Yellow Plan," a mobile content subscription service featuring a range of content based on Fox's "The Simpsons." For $9.99 per month, subscribers will gain access to Simpsons ringtones -- including the "Itchy and Scratchy" theme song -- as well as screensavers, wallpapers and other features. The plan will also allow them to play as Homer in Electronic Arts' "The Simpsons: Minutes to Meltdown" mobile game. Fox parent News Corp. paid $188 million for controlling interest in Jamba last September.
