YouTube on Thursday said that with the introduction of the new iPhone, mobile uploads to its site have shot up 400 percent.

Apple released its new iPhone 3GS last Friday, marking the first iPhone model to support video recording. It sold more than 1 million units in the first three day launch.

“This growth represents three things coming together from its new video-enabled phones on the market, improvements to the upload flow when you post a video to YouTube from your phone, and a new feature on YouTube that allows your videos to be quickly and effortlessly shared through your social networks”, Product Manager Dwipal Desai and Community Manager Mia Quagliarello said.
