I guess Nokia dont realy care about customers after they spent so much on these handsets..
Thats nothing else as firmware bug but no solution since first implementation on e-series..
Oh, well..

Is there any chance that integrated SIP protocol will cover sending text messages in near future..?

Why is that integrated SIP client keeps reconnecting even that Registration is on "when needed"..?
Also, why is that after call has been ended connection is still on..?
It has been like that on...
