It has been reported that iTunes access has been restored in China on Saturday after being unavailable since earlier this week. It is speculated that the catalyst for both events surrounds the “Songs for Tibet” offering which was featured prominently as a recommended download when iTunes became inaccessible and has now been removed from that section as Apple periodically refreshes those selections.
