Is support for the iPhone Retina Display in the pipeline?
At the moment it is not a big problem, the one quirk I’m having is that because the iPhone 4 screen is thinner, I get a small amount of scrolling to get to the bottom of a webpage. If I put a link down there, the next page will load scrolled down so I cannot see the top of the page. I guess you will support the screen fully but a quick fix could be to just make sure a new page always opens at the top.
