The article points to http://onefps.net/post/6496478249/50-percent-of-iphone-owner... which tells a somewhat different story.

One article sources "A little bird" and the other its own customer base. I wouldn't take neither as a definitive answer..

The stat people want to know is "Percentage of devices that shipped with iOS 3 that haven't upgraded to iOS 4". Grouping all the phones together doesn't answer that, since the iPhone 4 with iOS 4 will clearly be a big chunk that proves nothing about upgrade percentage.
