Apple tests push servers
Apple has begun testing its push notification servers, an unnamed source told MobileCrunch. The company allegedly sent invitation letters to a number of developers to download a pre-release Associated Press app for iPhone 3.0 beta 5. To stress the servers, the app has been intentionally configured to submit a large number of background push requests for creating a high-volume test environment.
The latest iPhone OS beta interface provides a new toggle to enable notifications globally. Users can also grant individual permissions for each app, with options for sounds, alerts and icon badges.
Early last month, Apple invited developers to begin utilizing push notification programming in app projects. A public release of the iPhone 3.0 OS should arrive sometime this summer.
