BBM is starting to get (kinda-sorta) rolled out today on iOS, and to get folks acclimatized, BlackBerry has posted a few how-to videos on their YouTube channel. Videos show how to manage groups, how read/delivered receipts work, handling multi-person chat, checking status updates, sharing files, and adding contacts.
You'd think for the occasion they'd shoot these on an Android or iOS device of some kind, but the overall UI doesn't change much platform to platform. It's all pretty straightforward, though potentially useful for those of you that managed to get in line for BBM early.
How many of you guys are going to be trying it out? Those that aren't, are you happy with your existing instant messaging options, or is there room for some competition? It's hard to beat the native integration of iMessage on multiple screens, that's for sure.
