Push notifications should be working. On iphone here's how you set them up.
Make sure you have the latest version of the app installed (there was just an update)
- Verify that Push Notifications are enabled on your device in Settings->Notifications
- Launch the app. You should be prompted to accept Push Notifications.
- Touch the "Notification Settings" icon on the home screen
- Choose "Create Account" and enter a user name, password, and valid e-mail you would like to use
- After you submit it, an activation e-mail will be sent to your e-mail address. Click on the activation link in that e-mail to activate your account
