Quite a few top tier BlackBerry apps got a nice boost when RIM first introduced their BlackBerry Messenger Social Platform SDK. This allowed third party developers to plug into the BlackBerry infrastructure and use it for peer to peer communication and sharing. RIM is promising more on this front for BlackBerry 10 but they have included this key functionality in BlackBerry 10 at launch. That means developers can already work with the BlackBerry Messenger SP API’s to make their BlackBerry 10 app supported.
Mark Sohm from RIM laid out the basic steps required to add BBM SDK functionality to your BlackBerry 10 app. Still there is one statistic for the BBM SDK on BlackBerry 6 & 7 now that really should entice you if you are a developer. “Approximately 2% of applications in the BlackBerry App World storefront have connected to the BBM SP; however, that group accounts for over 20% of all downloads!”
In other words if you want to prep your BlackBerry 10 app for viral growth check out the BBM SDK.
