We're pretty sure that Skype won't rest until its made every last carrier in the world squirm uncomfortably as they watch their old-guard business models flirt with obsolescence, and the next platform to get the treatment -- long overdue, may we add -- is going to be BlackBerry. The company has now taken a handful of signups to apply for a private, closed beta where users will be able to check out the goods in prerelease form, which hopefully means that a public release isn't too far off; between this, Windows Mobile, and the iPhone, they've now taken a pretty good chunk out of the smartphone market. Actually, we think we can see the shiny beads of sweat forming on carriers' foreheads from all the way over here -- except for you, 3. You're looking as cool as a cucumber.
