I too want this phone just as bad but I don't VZW is at fault here but Microsoft.  All the buzz on the internet is that Microsoft got into bed with AT&T for some reason and left the other carriers in the dust.  We will never no the true story here but hopefully in the coming months the phone will start appearing on other carriers or Microsoft will truly unlock the phones for all carriers upon release.

We have to wait till November to see what networks the unlocked phone can connect to.  Right now there is just a ton of speculation with no real answers.
