How does one implement a push notification for a blackberry app?
I heard that in order to do so I need to purchase a Blackberry Enterprise Server which costs me 1400 per year. Is this true? Where is a good starting point in implementing push notifications?
I am experienced with iPhone push development, but cannot find the equivalent for blackberries.
Earlier this year Blackberry launched a push service that does not require a BES, similar to Apple's offering. The have a Java SDK for it. You can find more information here: http://na.blackberry.com/eng/developers/javaappdev/pushapi.jsp#tab_tab_overview
