I also have the ppc6800 and am having the same problem with voice command 1.6. I spent quite some time with sprint dealing with this. They have no clue how to deal with the problem. call Microsoft was the suggestion. However, when ever you need to submit a trouble report etc, get out your wallet. I am at a loss as to turn to now. Does anyone have any suggestions.

One other issue- the service rep, when I asked her about Rev A, said that it is automatic when you are in a coverage age that has Rev. A. This is the opposite to what I have been reading. I was told that it a download is required. I travel a lot, and will be going to a rev A area next week (Dallas & Vegas) both of which are listed as having Rev A already.
