Compatible with iOS 4!
If you have activated your iPhone (original,3G,3GS,4) without an authorized SIM card (i.e. Hacktivated) and are running OS 3.x or iOS 4, then your push functionality is probably not working. The existing fixes haven't worked because there is only one certificate that many people are sharing. For the push notification service to work, every device needs a unique 1024 bit certificate. The certificate does not contain any information about your device, so I can provide certificates without any information from your phone.
If you used blackra1n and have lost YouTube, I have free YouTube fixes for that. WiFi and GPS not working? Click here. My free youtube keys don't cause excessive battery drain unlike the original push fixes.
Pushfix 2.0 is available here. It should only take around 5 minutes for 98% of you to get working. For those that need it, I have a ticket system for support issues at http://pushfix.info/ticket/. Please use it if you have any trouble, but do check the instructions and forum first before opening a ticket.
Web reviews of Pushfix 2.0:
MacHackPC.com : (ENGLISH) I personally used this fix and my push notification WORKS PERFECT!!! Its worth the money
RedmondPie.com : (ENGLISH) From all the testing I have done with it on one of my hacktivated iPhone 3GS, I can assure you that this thing really works as advertised. If you want Push Notifications on your unlocked iPhone, go for Pushfix 2.0. It is really worth it!
Blog4i.de : (GERMAN) The author states that he tried it himself and was thrilled that it worked and still does.
iphoneil.net : (HEBREW) The author states that he has tested the fix and confirms that it works. "Does this really work? Yes, it works!"
iPHONiX.fr : (FRENCH) Users confirm that it works.
I am also recommended by several application developers, but because of the Apple developer agreement they have agreed to, I won't state them here. The agreement prevents helping jailbroken users in any way.
