I'm quit new in iphone developing and I used to test my apps on my jailbreaken iPhone 3Gs without enrolling in the developer program. However, I needed to implement push notifications from my server but all the tutorials I found refer to logging in the provisioning portal to obtain App ID which I can't access without the developer program.
So here is the question: Can I implement the push notifications without enrolling in the developer program ?!
No, the required certificates and profiles for your server need to be generated by Apple, so you can't forge them.
