I have lost Blackberry connectivity on my Bold. I have a Rogers Bold running .190 on ATT. I get 3g without the Blackberry sign but there is a constant back and forth communication. When I change it to 2g, I get GSM. I am getting all my emails via WiFi. No one else in my office has this problem including one other guy who has the same equipment as me. I have done several battery pulls. Any suggestions??
