Ping the social networking service from Apple is now added to the iTunes for the iPad. Now the next time when you open the iTunes, you can spot an additional button Ping at the bottom. Using this, users can spot the activity of their favorite artists and keep tracks of updates from the artists. iPad owners also get the option to check concert dates of their favorite artists with a touch. We might have already tried out ping, so there is nothing different to talk about it, excepted the added functionality to the iPad.
