A low-profile iTunes event is scheduled for December 4th in Moscow, a leak suggests. One of Apple's Russian PR staffers, Irina Efremova, is said to have sent out an email invitation to a small group of people, indicating that a musical evening will be taking place at GUM, a shopping center in Red Square. Beyond that nothing is certain; it's thought, though, that it could mean that the iTunes Music Store will finally be opening in Russia in the near future.
