Oh hello, WES week! This is already shaping up to be one hell of a nice week for BlackBerry users. Not only did RIM launch BES 5.0 this morning, but it also announced that BlackBerry developers who are members of the BlackBerry Alliance Program now have access to a new API intended to serve even more push content to end-users. In a nut shell, devs who utilize the new API will be able to create or update existing apps so that they push new content to users as soon as it becomes available. This basically negates the need for manual or timed polling. Imagine, for example, sitting in a boring meeting when your BlackBerry’s status indicator lights up. Your favorite sports app informs you Roy Halladay has just struck out David Ortiz with the bases loaded to clinch the AL East mere moments after it happens. With the new push API, your BlackBerry will be able to do this in the near future — and that’s a good thing.
