iPhone 3.0 Push notification sample code & tutorial

I found the following two links quite helpful for me when developing iPhone Application using push notifications.

and

I also met with the following ERRORS:

Error in registration. Error: Error Domain=NSCocoaErrorDomain Code=3000 UserInfo=0x2910d0 "未找到应用程序的“aps-environment”的权利字符串"

Interestingly, I solved the problem with this post "I got the solution, when you have configured your AppID for Push notification, then recreate a new provisioning file with this AppID and install it on the Xcode Organiser, this has worked for me ." from the following link:

Some thoughts for building my dream

I should imagine more than what I can do now. And much more.

The ultimate goal should be big enough that you will try to fulfill it with my whole life
