This is too late for Blackberry to do anything now. The market is now abandoning BB in favor of iOS device in the Corporate Market. Android is too fragmented and it is very difficult for IT to support so many different version of hardware. So even Samsung is going to collaborate with BB on MDM solution, it won't have any chance to surpass Apple.
Some people said that the BB Passport can gain back some fans, but I think it is too late too. Now Samsung is also suffering from decreased sales, so it maybe another Microsoft + Nokia ending. Both dying company thinking miracle will happen
