title: iPhone window.open(url, '_blank') does not open links in mobile Safari
body: <p>I'm sending users to some .pdfs in a standalone web app (saved to home page, no PhoneGap) on iPhone/iPad. With <code>window.open(url, '_blank');</code> these documents open on top of the web app and since there is no back button there is no way to get back. Can I open these in a new window in JavaScript, or do I just need to use a real <code>a href</code>?</p>
