Apple's new iPhone 3GS has boosted mobile video uploads on YouTube by 400% per day since it went on sale last week Friday.

This growth represents three things coming together: 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, said YouTube product manager Dwipal Desai and community manager Mia Quagliarello in a blog post on Thursday.

Since Apple rolled out its latest iPhone 3G S, it said Monday it had sold over 1 million devices through Sunday, June 21.

Over the past six months, YouTube said it has seen a 1700% increase in mobile phone video uploads to its site.

With the iPhone 3GS, it offers features that allow users to record, edit, and share videos, unlike previous iPhone models.
