title: Is it okay to use <input type="tel"/> now?
body: <p>I'm working on a mobile phone web app and I have several text fields that could benefit from <code>&lt;input type="tel"/&gt;</code>. iPhones will adjust the keyboard for the user, but I'm worried about breaking backwards compatibility. What I'm hoping is that browsers/phone that support this can assist the user and other browser will fall back to a standard text field? Is this an acceptable practice? Does it even work?</p>
