For example, I'll go to engadget.com. When I go there the most up to date story is much earlier in the day. I'll refresh the page, and it brings it to the most current time. I'm not going to engadget through the history or a bookmark either, i type the url every time. It's not just engadget.com that does this either, that just happens to be one of the pages I go to the most frequently during a day. It seems to happen on only mobile web pages. I also have an iphone 4 that i did this test with simultaneously and the iphone never have the problem.
