iPhone Theme Store

There have been many reports of wifi and push notofication issues after the iPhone 3.1.2 jailbreak with blackra1n and unlock with blacksn0w.

Plus, there has also been issues with Youtube and GPS after the 3.1.2 jailbreak.

But, we are in luck as iPhoneil has released a ‘Push Fix & Youtube’ and is now available in Cydia.

1. Disable Wifi before you start
2. Just add the iPhoneil repository to your Cydia sources – http://cydia.iphoneil.net. Search for Push Fix &  Youtube and install it.
   
3. Now, reboot your iPhone and enable WiFi.
4. Reboot your iPhone again

Looks like this patch fixes the wifi & Youtube issues after the jailbreak/unlock with blackra1n & blacksn0w.

Let us know in the comments if this helps such issues you had with your iPhone.
