    Modem firmware / baseband 5.15.04 can not be unlocked.

    It is possible to install the iPad baseband 6.15.00, then Ultrasnow and unlock.
    Warning: This will break GPS accuracy. Locations services will still work.

    To install the iPad BB, download redsnow 0.9.6rc18, and iOS 4.2.1
    Run redsnow and select one option 'install iPad baseband'

    If not already installed, use Cydia and install Ultrasnow.

    Sounds like the phone was never activated, it's also possible that the phone is a non-apple refurbished phone. If you got it from the carrier, restore it to original confit and return.
