Hello everyone.
I got my 6700 about 2 weeks ago from upgrade on 3 and soon found out that this bluetooth problem - always freezing on the switch-on screen.*I have tried all the methods that were mention in the above thread but none of them could keep the bluetooth on permenantly. I contacted the customer services and visited the 3 store but they were not very helpful either. However before I set out to fight for a replacement I think it might be worth a shot to mention an interesting finding about this problem here as I have never read a similar description before.
When I take the Sim card out of the mobile and switch it on to work under no sim-card mode. The blue tooth can be switched on and off as many time as I want and can work perfectly. But when I fit the Sim-card in and switch it on just after a few minutes*the connection*will be*off again.*This won't sort the problem anyway but it*gives me one thought. Is there a possilbilty that Sim-card will interfere the blue tooth function? It's quite weird as I never heard that before. Hope this information would be helpful for someone somehow.
