HBO has released the iOS application for its new HBO GO streaming video service providing subscribers with an iPhone, iPod touch or iPad with access to over 1,400 HBO shows directly on their devices. Available at no additional charge for existing HBO subscribers, HBO GO allows users to view programming over either a Wi-Fi or 3G connection, making the entire lineup of HBO shows and movies available while on-the-go. Bonus features and special behind-the-scenes extras are included in the HBO GO service and the app allows users to also create customized watchlists and smart “Series Pass” lists to easily follow their favorite shows. HBO GO is available only in the U.S. and requires a 3G or Wi-Fi connection for viewing content. The universal iOS app requires iOS 3.2 or later and an iPhone 3GS, iPhone 4, third- and fourth-generation iPod touch or iPad. HBO GO is available from the App Store as a free download.
