Me thinks that Research In Motion sees the writing on the wall: Blackberry will ultimately not win the smartphone or tablet wars. Today in Orlando, RIM announced it's Blackberry servers for the enterprise will soon be supporting other platforms, including Android and Apple's iOS.

RIM's leap into multi-platform support will come from Ubitexx (which it announced it is buying almost in the same breath today at Blackberry World in Orlando).
