F-series model: F-90BT (Firmware 2.0 and bluethooth update 3.30 RC3)

Phone book transfer: Haven't tried this yet
Sound quality: Very good, I have no complaints at all
Comments: Works well, not the slightest issue with it so far in terms of general phone use. Haven't tried the voice dialing or the phone book transfer yet.
