title: Protractor test fail on iPad using sauceLabs
body: <p>I'm not able to run my protractor test using the iPad. The desktop browser tests are working fine. Here is my configuration: </p>
  
  <pre><code>exports.config = {
  
    sauceUser: "xxx",
    sauceKey: "xxx",
  
    allScriptsTimeout: 120000,
    specs: [
    'smoke.js'
    ],
  
    capabilities: {
      'appium-version': '',
      platformName: 'iOS',
      platformVersion: '8.1',
      deviceName: 'iPad Simulator',
      browserName: 'safari'
    },
  
  
    framework: 'jasmine',
  
    jasmineNodeOpts: {
      defaultTimeoutInterval: 120000
    }
  }; 
  </code></pre>
  
  <p>And here is the output: </p>
  
  <pre><code>/home/ubuntu/workspace/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:113
    var template = new Error(this.message);
                   ^
  UnknownError: The Sauce VMs failed to start the browser or device
  </code></pre>
  
  <p>Is there something wrong with my capabilites configuration? </p>
