RIM's Asia/Pacific region got this BIS 3.2 update this past weekend. I know that already.
The usual schedule for BIS upgrades from RIM is that the AP region gets it first.
A week or two later, the Europe/Africa/MiddleEast gets the update and a week or two following that, the Americas will get the update.
So, on my calendar, roughly, that would mean North America would get the update either October 10 or 17th, and when we hear that Europe has gotten the update we can pin that down more firmly.
Plus, RIM might put out to its top tier tech support customers the routine outage scheduled for XX dates, which will confirm it.
