Yes error 10xx just means iTunes didn't (couldn't) update your baseband, which is a good thing, because updating the baseband usually results in an unlockable baseband, and you can't downgrade basebands.

ya 4.3 upgrades them all to 05.16.01 and you can't unlock that baseband. Do you think there will be an unlock at some point.

At some point, sure. The point is, you can upgrade to 4.3 and keep your existing baseband, if you use custom firmware. Or, if on a iPhone 4, TU itself will preserve your bb.
