After Apple launched the iPhone we’ve seen all sorts of statistics and lots of numbers depicting its success. Today we’re in for a different perspective. YouTube says that its mobile video upload has increased by 400% after the iPhone 3GS has been released. It seems that everyone has been anxious to upload their first recorded video with the iPhone 3GS and we will probably see even more mobile videos uploaded to YouTube soon since the iPhone 3GS will go to 70 more countries.
