HBO's free iOS streaming software is a nice companion app provided you're already subscribed to the service.
And if you believe the continuing ramblings, the Time Warner-owned premium cable network is considering offering additional subscription options in the not-so-distant future, potentially allowing cable-cutters to subscribe to HBO for online-only access.
In the meantime, HBO has updated its Go app for the iPhone, iPad and iPod touch with two new useful features. The first will appeal to the fans of HBO's Game of Thrones series as they can now enjoy enhancements related to the show's interactive experience. The other improvement includes AirPlay multitasking capability. What's that, you ask?
