This was on Appleinsider today, so I don't know if this generally warrants a news item, rumor item, or even a Mac item.

AppleInsider | BlackBerry maker in "confidential" hunt for iPhone developers

The reported wording from RIMM's internal posting seems pretty vague to me. Personally, I hold out hope that this internal effort goes toward a better sync solution on the Mac platform rather than some sort of BB for the iPhone.
