Not sure what has happened. I am on CM7 build 20.
I installed the new market yesterday. My voice search has been acting up, saying 'connection failed' so I uninstalled it and went to get in the market to re-install to see if that would correct it like it has in the past. When I hit the Market button it just says, 'No Connection'.
I had Juice Defender installed and thought that might be somehow disabling data so I uninstalled it as well but still have nothing.
