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).
