BlackBerry Push APIs: Accessing the Power of BlackBerry Push Technology
Source: Research In Motion
One of the cornerstones of the BlackBerry solution has been the ability to proactively deliver, or "Push", data to BlackBerry devices. BlackBerry Push Technology has been used to push emails to users and to synchronize calendar information. However, although BlackBerry Push Technology has been available to developers creating enterprise-based solutions for BlackBerry users registered with a BlackBerry Enterprise Server for some time, until now, it has not yet been available to those wishing to develop applications for BlackBerry users outside of an enterprise environment.
