While I have some RIM contacts and a lesser degree of Cingular contacts, I try not to bother them with issues that are not in a critical path. I have mentioned expanding theri coverage of Bluetooth car kits but I suspect that this is not very high on their priority list. If you can find 4.1 firmware that is not Cingular for your device and it will provide you the functionality you need, use it. I do. On my 7290 I use the Hong Kong version because it supports the address book. I use the Hong Long version on my 8700 because I hope it has fixes that are not in the earlier releases. I have not experienced problems with either on Cingular througout the U.S.
