“Despite licensing the proprietary ActiveSync Exchange Server protocol from Microsoft for use with the iPhone, Apple is building its own Push Notification Server for messaging services in both the iPhone and Mac OS X Snow Leopard Server using open, interoperable standards,” Prince McLean reports for AppleInsider.
“However, the company’s pioneering, yet protracted leap into push messaging indicates that notification technology can be more complex that it seems, having delayed Apple’s intended deadline for shipping PNS by many months,” McLean reports.
“Last year, Apple introduced plans at WWDC to provide a third push mechanism for the iPhone, in addition to Microsoft’s Exchange ActiveSync support and MobileMe. Rather than pushing updated contacts or calendar messages, the new Push Notification Server (PNS) would allow third party developers to push notifications of any type to the iPhone, which would then badge the application’s icon, alerting users that the application had new information waiting for it,” McLean reports. “However, Apple indicated that PNS was supposed to ship by last September. That deadline came and went, and the service was never rolled out.”
