Once the press started pushing the story of Kik messenger and the oddity of it getting banned by RIM, they have now released an official statement.
“RIM became aware of a number of issues and customer concerns regarding the Kik app and service. Following discussions with Kik, the app was removed from BlackBerry App World on November 12. Upon further investigation, RIM concluded that Kik had breached contractual obligations. Based on the broad scope and seriousness of the issues and concerns, RIM terminated its agreements with Kik and withdrew RIM’s support for Kik’s service.”
It isn’t exactly the clearest statement, as they don’t go into much detail. However, it does not appear that Kik will be allowed back onto App World and quite possibly on the BlackBerry platform.
