So far, iOS has been more successful than Android in the enterprise sector. Android hasn't had anywhere near the same impact on enterprises as on consumers, thanks in part to a fragmentization that drives up support and management costs, according to Wallin.
To get around that, enterprises should standardize on a small number of specific device types, MobileIron wrote in a white paper on BlackBerry migration. It's also best to start with the basics, like standardizing email, before moving on to more advanced management activities, the company wrote.
Allowing multiple OSes to be used isn't just about management: "A lot of people don't seem to think too much about how much more expensive data and call plans will be. Data usage on an iPhone compared to a BlackBerry is massively higher," said Absalom.
Good Technology and MobileIron aren't the only vendors that offer software to help replace BlackBerry smartphones. Other alternatives include AirWatch, Citrix Systems, SAP and Samsung, according to Wallin. Absalom adds Fiberlink, BoxTone, Soti and Apperian to that list. A potential starting point is also BlackBerry's own cross-platform offerings, he said.
However, BlackBerry isn't giving up without a fight. It is still a "brand with enormous potential -- but it's going to take time, discipline and tough decisions to reclaim our success," Chen said in statement on Monday.
