Ideally I would like to use Safari, since it's a native app, which is good for performance, and certain things open it automatically anyways. But I use the Mercury browser now. One reason is the ability to sync my bookmarks with Chrome, which is what I use on my desktop. The other reason is the gestures to instantly go to the top or bottom of a very long webpage. I think it has pretty good performance too. But I haven't spent a lot of time with a lot of browsers. What do you guys think is the best browser currently for iPhone?
