In the midst of the BlackBerry World event currently underway in Orlando, Research in Motion (RIM) issued a statement Monday night claiming responsibility for a series of anti-Apple flashmobs that took place in Melbourne and Sydney.

The admission comes after a flurry of media reports had pointed at RIM as the arbiter of the flashmobs, though popular opinion on other tech sites had cast Samsung as the most likely competitor to have engineered the stunt.

Video of the flashmob protesting outside an Apple Store in Sydney has made the rounds on YouTube, showing black-clad men and women filing out of a bus holding signs saying, “Wake Up” and chanting in front of the store. Onlookers crowded around, some with bewildered expressions.

In a brief statement on the incident, RIM stated that “a reveal will take place on May 7th that will aim to provoke conversation on what ‘being in business’ means to Australians,” without elaborating further on what that actually means.

It’s believed that this “Wake Up” stunt is part of a campaign RIM will be unveiling to promote the BlackBerry 10 operating system, which RIM CEO Thorsten Heims introduced and previewed at a BlackBerry World keynote. Look for more coverage from the show floor from our very own Gadjo Sevilla.

BlackBerry 10 is being anticipated as the last concerted attempt for RIM to become a viable competitor in the smartphone market after ceding significant market share to Apple and Google, who now dominate the category.
