I would hope that the delays of the firmware is a least due to fixing the top bug on my list. The one about bluetooth with car-handsfree and handsfree units in general. There are many reports with the same problems as I have with the poor sound quality. With my own HCB-108 (SE) carkit it's actually completely useless to have a conversation, there is a robotic voice, acoustic feedback and complete sound dropouts. That carkit works perfect with other phones, even with Nokia's own E66. Some say it's because of interference with WLAN (since it use the same frequency band), but to me it doesn't matter if I turn that off or not.

I'm not complaining here, just saying that I'm willing to wait very long for the next firmware (PR1.2), just as long as this basic bluetooth functionality gets fixed. I am following any new on that one in bugzilla, but I'm sad to see it's still unresolved (#6766). There doesn't seem to be much activity on that one and no info from Nokia (as usual).
BTW, has anyone the flashed the leaked PR1.2 tested using handsfree bluetooth units and noticed any improvement?
