Those who desperately need to watch tomorrow’s inauguration on their iPhone are in luck. Just in the nick of time, Apple’s App Store approved the Ustream iPhone Viewing Application.  It’s only available in WiFi “to ensure the highest quality broadcast on the iPhone.” That may change in the future, the company says.Of course, it’s not only for watching the 44th president take the oath of office. iPhone users will be able to “watch and chat with any Ustream show” via their phone. You can download it here.
