title: Unique device identification for ios
body: <p>I have a HTML/JS/CSS app which I wish to convert to an ios app using phonegap. In my application, I require to identify each device uniquely. From iOS 7 Apple does not accept app that Fetch UDID. I want to achieve this for ios4+ to latest. I have seen one plugin listed at  <a href="https://build.phonegap.com/plugins/1112" rel="nofollow">https://build.phonegap.com/plugins/1112</a>. One additional question related to this plugin is if I use a plugin which relies on keychain then what is the risk factor, i.e., under which circumstances is the keychain reset or cleared?</p>
