After Apple repeatedly rejected the iPhone version of its mobile app, streaming music service Grooveshark is going around the company's formal App Store and making it available through the underground app community Cydia.

Cydia is where users of "jailbroken" iPhones-devices that have been hacked to allow them to run any software and operate on networks other than AT&T-find pirated versions of official iPhone apps as well as apps not submitted, rejected, or otherwise not available on the iTunes App Store.

In a post on TechCrunch, Grooveshark makes the curious claim that Apple rejected the app for "primary selfish reasons." What the post doesn't mention, however, is Grooveshark's legal problems. Universal Music Group still has a copyright infringement lawsuit against Grooveshark outstanding. Grooveshark's only major label licensing deal is with EMI, which only came as part of the resolution of a lawsuit that label had placed against it earlier for similar reasons.

How those legal problems have contributed to Apple's rejection is unclear, as both BlackBerry and Palm app stores have approved the app.

Grooveshark is a music search engine and streaming service that offers a free, ad-supported tier and a $3 monthly premium tier. Users can save playlists of searched songs, and the service also offers a recommendation engine that builds playlists around a user-defined "seed" song. Users can upload songs to the service, which labels can ask to have removed via a Digital Millennium Copyright Act takedown notice.
