iPhone 4 Push Notifications Not Working After Restoring iOS 4.3.5

Hi, I asked my daughter to restore my iPhone to iOS 4.3.3 yesterday. However, she updated my iPhone 4 to iOS 4.3.5 and I have noticed that the device’s Push Notification is not working accordingly. Is there a way to fix this? Thanks in advance.

Hello Rudy, You will not be able to restore / update your iPhone 4 to iOS 4.3.3 due to the fact that Apple already stopped signing this firmware in order to prevent iOS device users (specially iPad 2 users) to jailbreak their device using JailbreakMe 3.0. Anyway, regarding your issue, iOS’ Push Notification system is broken. To get a fix from Apple, we still have to wait for Apple to release the final version of iOS 5 firmware to the public. If you aren’t aware, Apple’s new iOS 5 firmware for the iPhone, iPad, and iPod Touch will feature a completely revamped iOS Notification system, which was created by the popular jailbreak app developer Peter Hajas.

However, this issue can be fix once you jailbreak your iPhone. If you want to jailbreak, then you can follow this tutorial on how to jailbreak iPhone 4 on iOS 4.3.5 using Redsn0w 0.9.8b4 for Mac OS X and Windows.

Anyway, to fix iOS’ Push Notification you will need to download and install an app from Cydia Store called Push Doctor. You can refer on this guide on how to download and install Push Doctor on your jailbroken iPhone 4. If Push Doctor does not work, then you will need to activate your iPhone using SAM to ensure that all features of the iPhone will work smoothly on the jailbroken iPhone. The step by step guide on how to install and use SAM can be found on this blog post. That’s it.
