BBPush is a simple server-side Blackberry push notification client that works with any BIS applications, regardless of it is in development or in production. All you need to use it are the Blackberry PINS of the devices you want to reach and a few configuration properties that you can get from the BB app developer. The library makes it trivial to send push notifications, be it for one PIN, multiple PINs or even all devices that have your app installed.
