I just got confirmation from one of our longtime readers, another Ronen, that the BlackBerry Unite version from Bell works on AT&T and is not carrier dependent!!!
Pretty amazing stuff. He got the Bell-Canada copy, installed it and it is working amazingly on his at&t blackberry. It looks awesome, can sync and share: Calendar, Contacts, access all your local PC files remotely, manage (wipe, lock, report on etc.) the devices OTA and more.
Only major disappointment is that it does not handle Tasks or Notes Why would RIM ignore that part I don’t know. So it is not really a personal BES replacement but it is pretty close and free so can’t argue with that.
A friendly birdy told me you could pick it up from this link:
Anyways, just FYI , it is NOT carrier dependent (meaning you can download the Bell Canada version, install it and run it just fine, at least over at&t wireless) and does not require any carrier activation. You just plug your blackberry via USB once and activate it that way.

You can get a lot if information from it.
Attached are a couple of screenshots (installation process).
