I have the phone and love it!!! I've had it for over a month and a half now. Used to have the V600 and in terms of functionality it is pretty much the same just in a much nicer casing.

No problems with BT or charging the phone. I charge the phone via the USB cable connected to my laptop. BT headset is charged using Igo.

I love it because the keypad is great. Nice and thin and feels great in the hand. Haven't had any problems with OS. Find it much faster than SE T616. Used to be long time Nokia user and switched to V600 which was okay, but now the V3 is great!
