I upgraded to 2.0.1 on my 3G iphone, after I did so it came up with a message saying that it needed to do a carrier update. This failed with an error. Since then I don't get prompted to update carrier settings and my incoming caller ID doesn't match my contacts (i.e. incoming = 021 123 4567, my contacts = +6421 123 4567)

Is there a way to force iTunes to resync the carrier settings?

Thanks
