A855 for Verizon, How do I unlock it?

[chunnel]

I just purchased an A855 for one of my lines, but found the original phone, so I don't need it. I could return it, but I'm seeing that I might be able to make a nice profit by selling it on Amazon for double what I paid if I can sell it as unlocked. I am experienced with WinMo, but not Android, except for running Android non-natively on my Touch, TP and TP2.
