  1. I am not able to use bluetooth on my iphone4 which I bought couple of weeks back. It identifies the other device but doesnt transfer or let any other device send too. Pls advice. Thanks

  2. Restoring factory settings will upgrade the BB too and users will loose their unlock. I’ll instead vote for Cydia method. What say, Anurag?
