Only one month after the initial release of push notification, Apple has invited iPhone OS 3.0 developers to participate in high-volume tests of the system. If all goes well, push notification is expected to be operative for general users with the release of iPhone 3.0.
Push notification saves the iPhone battery by allowing apps to receive information without actually running in the background. Recent reports have indicated that Apple is considering allowing a limited number of apps to run in the background, however this taxes iPhone resources.
For the vast majority of applications, background push notification provides an efficient compromise solution. Release of push notification was expected last fall, however Apple underestimated demand for the service and had to redesign the system.
The test uses an Associated Press news app, and will be active for one week. Here's the text of the invite sent to developers:
Help test the Apple Push Notification service
As a developer actively working with iPhone OS 3.0 beta, we would like your help in testing the Apple Push Notification service. We have selected a pre-release version of the Associated Press app for iPhone OS 3.0 to create a high-volume test environment for our servers.
To participate, we ask that you follow these steps:
1. Download the pre-release version of the Associated Press app for iPhone OS 3.0 from the iTunes Store via your desktop by entering this unique redemption code in the ‘Redeem’ section of iTunes, found under the ‘Quick Links’ section. This unique redemption code and the functionality of the application will expire in seven days.
2. Install the application on a development device running iPhone OS 3.0 beta 5 by synching it to iTunes. Make sure to accept notifications when prompted after installation. This application can only be installed on devices running iPhone OS 3.0 beta 5.
3. When you first run the app, choose U.S. English as your region when prompted. The U.S. English region will receive alerts, the Canadian English region will not. For purposes of the test, AP will be sending a high-volume of real news alerts.
4. If you do not receive notifications from the app within 48 hours after installation, let us know.
We appreciate your assistance,
iPhone Developer Program
