RIM has a great solution, but they're a challenging company to work with. We've seen them change a lot of their policies on how they will provide ongoing support for the BlackBerry Enterprise Server. |
RIM is organized, from a management perspective, around carriers, and partners that succeed are able to work around those parameters. If RIM were to open up that strategy and have a channel and work with third parties, I imagine they would do it delicately in order to remain carrier-agnostic. |
The big knock against the BlackBerry solution is that it's somewhat of a walled garden. |
