Facebook on 1 million BlackBerries, 16% login daily

Facebook for BlackBerryResearch In Motion, maker of the BlackBerry, yesterday announced that the Facebook for BlackBerry application has surpassed the 1,000,000 download mark. That’s a lot of socializing happening on productivity devices.

Facebook for Blackberry allows users to view messages, photos, pokes, and wall posts, but not view profiles or respond to friend requests. I’m curious how Facebook for Blackberry usage patterns compare with those of Facebook for the iPhone.
