Reading through this thread, it's obvious that you are well in touch with RIM. But how about the Cingular side? Specifically:
My 7100g is barely Bluetooth capable with car kits, but firmware 4.1 is supposed to correct many of the issues. I know that an international release has been made, but Cingular has not yet "blessed" it. Any there any insider info to be had regarding an approval date?
Also, reading back several msgs, there was a request for RIM to add non-OEM carkit (i.e. afermarket) compatibility info to their Knowledge Base article. It would be great if they could publish info on the major players - Motorola, Parrot, etc.
