Orb’s iPhone application was previously only available on jailbroken iPhones. The application connects with the Orb software installed on a Windows PC. A TV tuner on the PC provides DVR abilities, as well as placeshifting both recorded and live content. The program works with Windows XP and Vista Home Editions, as well as supporting Media Center in more advanced versions of Windows.
Unlike the jailbroken version, OrbLive costs $9.99. More importantly however, it has to play by the rules of the App Store. Meaning, OrbLive will only stream television over Wi-Fi, and not a 3G connection. Apple has indicated to Slinbox and other competitors that live TV streaming will be treated as VoIP, and only permitted over a Wi-Fi connection.
Update: Orb has updated their application, enabling EDGE & 3G streaming of Live TV. Read more here.
