Last week, I reported that BBM would finally be coming to Android and IOS this weekend.  We then saw the IOS app appear ahead of schedule on some international iTunes stores (US was confirmed to me). 

Yesterday we heard that Blackberry was halting the roll out due to a leaked Android version. This version had been illegally used by 1.1 million users causing the Blackberry systems to strain. 

Those who managed to snag the official IOS version will still be able to use it. Those on the illegal Android version will see their app stop working shortly.
