Sorry for the bad spelling - wrote on the cellphone... Anyway, the BT headset I am using is called HTC BH S600. I have used it without problems with an Iphone 5. Historically, Iphone has had lots of problems with Bluetooth so I am surprised with Ericsson having such fundamental problems.
I have nbow tried a second pair of BT headset. Jabra 3030. Exactly the same issue. Was recommended by support to do a restore using PC Companioin. Trying that now... Takes ages, thoguh...
