Had my BB for a month now -everything worked fine except whilst in my house I had really bad interferrence on voice calls.
Had the handset, SIM & battery all changed but no cure.
Started playing around myself and found that when I disconnected the phone from the WIFI the calls were fine.
The phone is on Orange and the WIFI is Sky Broadband in the UK.
Anybody else had this issue - any ideas how to over come?
