We are here to solve the main problem for iphone push services,, its all apple do it to use official SIM,, if you using official sim then this is not for you,,,
How it is attached to Push Service
When you unlocking your device using GEVEY sim or using Ultrasnow,, its bypaas the network activation Proccess and therefor your push service keep blocked,,, most of app not working like, Facebook, whatsapp, google+,, almost all important app.....
How to solve it,,,
First of all You will need a jailbroken, already-hacktivated iPhone 4/iPhone 3GS, with Cydia up and running.
First, launch Cydia, head on to the Manage tab and add the following source.
Once your new repository is added, search for SAM, or find the package in the repository manually, and install it.
With SAM installed, you’ll find a SAMPrefs icon on your iPhone’s Springboard. Launch SAMPrefs and navigate to Utilities .
Under Utilities, tap the option that says “Revert Lockdown to Stock”. This will deactivate your hacktivation, but don’t worry about it; your iPhone will remain functional.
A message will pop up claiming that Stockification was a success. Hit OK to dismiss.
At this point, the activation is basically complete and you can verify that by navigating to Settings > SAM > More Information. If it says Wildcard Activated, you’re good to go.
From here on begins the part that requires patience (bothered me, at least). Reboot your iPhone and then let it sync with iTunes. Once that is done, install the free iPusher app from App Store [iTunes link].
Note: If you dont have WIFI ipusher will not work but dont worry, just try any application to try your push notification,,,
