    unfortunately when you restored it also upgraded to last version of IOS which currently uses a baseband that is (as of right now) unlock able.

    to get basic function back use limera1n to hactivate, but to get phone and messanging (as well as 3g/edge) usage back you're going to have to put out for an AT&T sim till someone figures out how to unlock this baseband

    I thought you couldn't downgrade the baseband, though?

    This would be better suited for the Jailbreak Forum and a question Farbod could tackle!

    No you cannot downgrade baseband. Supposedly newest unlock will be released after 4.2 is released to the masses, but even then it might be a little while before it's ready.
