If it's Verizon, you need to load CDMA/EVDO firmware, not UMTS firmware.
Which is why you get the wrong configuration in the dialog that asks for
a "Plan Name".  Try directory '1' perhaps; I have these MD5 sums:

06f76ed398458dad7b91c2d99a85a0a7  1/amss.mbn
88a60ed745d75fb1b92c539574ecc972  1/apps.mbn
e4d8d4dbd0a10d17f01f7f3bbd2ea734  1/UQCN.mbn

One way to check is to do something like:

cd /where/your/firmware/is
strings 0/* | grep -i vzw
strings 1/* | grep -i vzw
strings 2/* | grep -i vzw
strings 3/* | grep -i vzw
(etc)

until you get a hit for something, like @vzw3g.com.
