Blackberry's push notifications are now available to any developer who'd like to stick 'em in any Blackberry app. Since battery-friendly push is the best part of owning a Blackberry, this update sounds fantastic.

I wanted to let you know that RIM is now generally offering the BlackBerry Push Service to all BlackBerry developers. Any developer building on the BlackBerry platform can use BlackBerry Push to drive content to their customers as quickly as possible, giving people a fast and easy way to get the information they want.

What is the BlackBerry Push Service?
More than just an alert! The BlackBerry Push Service allows an application to give the user immediate access to information that no other platform can provide in quite the same way. The BlackBerry user sees a notification appear, letting them know that one of their applications has new information for them. They can quickly go to that app (without having to shut down anything they are currently doing) and the new information is right there. Users don't have to open the app and download the new information, the new content has already been pushed (BlackBerry developers can push up to 8KB of content in each push).

It's not a notification that tells you to go get information, it brings you the information. Other platforms flip the flag up on the mailbox, letting you know it's time to go to the end of the driveway and get your mail. BlackBerry Push delivers the mail to your kitchen table, open and ready to be read.

But wait. There's more…
Applications leveraging BlackBerry Push Service don't have to compete with other applications that are receiving pushes. One application's latest push won't trump another application's existing push – users won't miss their chance to see all the latest information available to them.

The BlackBerry Application Platform allows applications to run in the background and when new information is pushed to the device from the application server, that app wakes up and provides the content to the user. The app is not constantly asking servers to see if there's new info. You don't want to know the weather every 15 minutes; you want to know when it will affect you – immediately. Another plus for BlackBerry users is optimized battery life. The repeated polling for information that other "push" products require is likely to result in additional battery drain, compared to BlackBerry Push Service and could cause excessive traffic on the application's servers from constant requests.

What is being made available today?
The BlackBerry Push Service has two options: BlackBerry Push Essentials is a free service that developers can incorporate into their applications and allows them to push content to their customers with unparalleled immediacy. BlackBerry Push Plus which has a free tier and paid tiers, provides developers with notification that their push has been delivered. If a content provider needs to get information to someone, they can tell if the target device has received the push.

There's a diagram on BlackBerry.com that gives a good visual representation of the infrastructure behind this service:http://na.blackberry.com/eng/developers/javaappdev/pushapi.jsp#tab_tab_works

Is anyone using this service yet?
Companies using the BlackBerry Push Service include Time, Sports Illustrated, The Hockey News, and Weather Bug Elite. Here's a link to some additional examples of developers who have already deployed applications leveraging the BlackBerry Push Service for you.

How can developers get this new service into their applications and corresponding server?
Developers building on the BlackBerry platform can visit www.blackberry.com/developers/pushservice for additional information, resources and tools. And there's no cost to register and evaluate this service. When a developer is ready to launch the service, they can choose BlackBerry Push Essentials or BlackBerry Push Plus, depending on the implemented features and number of pushes.
