Grooveshark is one of the most popular online music streaming service provider and they have now launched their iPhone app to serve their users even better. Though this app is still not available via iPhone App store, chances are that it will soon be available to download from there.

Grooveshark say’s :

Right now there is not a Grooveshark application for iPhones through Apple’s iPhone App Store. Unfortunately at this time, Apple is unwilling to work with Grooveshark to approve our application.

The application can be download via Cydia on Jailbroken iPhones. Currently they are offering limited features in their app which lets you listen to the latest music on radio, create your own music list, listen it offline, etc

Currently, this app provides numerous facilities like play or preview songs, save and make Playlists,  listen live online radio, listen to your favorite tracks offline and enjoy almost any International radio station you want to.
