Is it possible test the Apple Push Notification Services without an iPhone application? (Creating an emulator on windows?)
If isn't, how could I test that? Is there a free sample application compiled to do that?
I created the Server provider, but I need test the functionallity.
This answer is outdated. As of 2020 / Xcode 11.4 it's now possible to test push notifications in the simulator
See this full explanation in a answer below
Sorry to say, but you'll need to find some hardware to test this functionality.
Push notifications are not available in the simulator. They require a provisioning profile from iTunes Connect, and thus are required to be installed on a device. That also means you'll probably have to be accepted into the apple iPhone developer program and pay your $99.
On the bright side, with the iPhone OS 3.0 update, you can test this functionality on any device, including the first gen iPhones.
