Hi, I’m using Appium 1.3.4, when I do the following config setup, my iPhone 8.1 tests will always run against iPhone 6… Can anyone please tell me how to force my tests running on iPhone 5S? Many thanks!

```
 "ios81": {
        "browserName": "",
        "platformName": "iOS",
        "platformVersion": "8.1",
        "deviceName": "iPhone Simulator",
        "app": ""
    },
```
