It's official. HBO content just entered the digital halls of iTunes with variable pricing. Episodes of Rome and The Sopranos pop for $2.99 while The Wire and Sex and the City (yes the complete series) go for the iTunes "standard" pricing of $1.99. We just fired-up iTunes and confirmed it just like the rumor predicted. With Apple backing down from its strict, flat-rate pricing policy, don't be surprised to see additional content from previously iTunes-shy providers arriving in succession.[Thanks, Turki]
