iOS Push Notification Works in Apps Installed via Xcode but Not Installed via iTunes
Two easy steps to check and resolve this issue:
1) If your iOS mobile device is capable of using the cellular data network, check that it has an active cellular data plan. Turn off Wi-Fi in Settings and see if you can still browse the web with Safari, for example. On the other hand, if the push service is using Wi-Fi, any firewalls between your device or computer and the Internet must allow TCP traffic to and from port 5223. To check open ports, you can use: netstat -an
2) Make sure you are using "gateway.push.apple.com" and not "gateway.sandbox.push.apple.com".
