 The `sync` method can be called anywhere you'd like to check for an update. That could be in the `deviceready` event handler, the `click` event of a button, in the callback of a periodic timer, or whatever else makes sense for your needs. Just like the `checkForUpdate` method, it will perform the network request to check for an update in the background, so it won't impact your UI thread and/or JavaScript thread's responsiveness.
