iphone-push-notification-service The push notifications for hactivated (jailbroken and unlocked) iPhones never worked properly until PushFix 2.0 was out with a working solution. PushFix fixed the issue by providing each iPhone a unique certificate generated via IMEI number of the phone for $5.99. ‘Push Doctor’ is a free push fix solution that uses same unique certificate issuing technique. Push Doctor is created by Anethema and CmdShft.
