What will happen if I load the new Facebook for BlackBerry onto my RIM BlackBerry Curve 8310 (which I previewed in New Adventures in GPS)? Will CrackBerry + Facebook = the annihilation of my little remaining productive time?

My colleague over at Computerworld, Ulrika, has already taken the plunge, and as a more advanced Facebooker than myself is only so-so impressed. Looking at Facebook on the screen of her BlackBerry, it looks to me like most of the basic functions are in place - including the all-important Status Update and Poke, plus the ability to add friends or upload photos - but not the open platform apps that so many people love.

Facebook: your new HR software
While some employers are busy banning Facebook (now part-owned by Microsoft), it's easy to see why the canny Research in Motion, maker of the BlackBerry, is lending its support.
A mob in Sydney called Serena Software has not only OK'd Facebook, but is positively embracing it with "Facebook Fridays" during which its 800 staff are actively encouraged to network with family, friends and customers via the soc-net site. It's the way to reach "Generation Y", Serena's CEO reckons.

And Fortune's Brent Schlender says "Facebook makes me cringe" before admitting it could be the mother of all HR systems for keeping a company's staff on the same track.
