F-series model: F90bt
Phone make/model: Verizon LG Voyager(VX10000)
Ease of connection: Easy. Set F90 to search, and made the voyager "visible" to it.
Phone book transfer: Fast. Probably about 45 seconds, and I have well over 100 contacts with multiple numbers for each.
Sound quality: I can hear people i call very well, and they can hear me very well. Even did a three-way conference call, and it was crystal clear to everyone!(We all had verizon, and the friend i called did the conference from his phone)
Comments: Doesn't seem like the F90 supports the voyager's text seei
