When i searched I found many people are having this issue with their iPads, but the exact same thing is happening to my iPhone. It seems to happen when you try to click on a highlighted/underlined link someone, for example, stuck into a post of theirs. Safari appears to open that page in a second window, but the window stays blank. If you go back to the original window with the link, then go back to that second window it opened for that link, now, magically it's there. I saw many people post about it in the iPad section but not about their iPhones. Well, it's definitely happening on my iPhone 4s eith 5.0. It seems to happen on manually inserted links, like: here, check this out, then they copy/paste a clickable URL/link into the body of their post. Click on it, opens it in a new window, only, that page is blank, until you go back to the first page, then go back to the new page again, now it's not blank. Anyone else?
