First, did u unlock using sim proxy ? If yes, than it's normal to happen like that. That is why, unlock iphone 3G using sim proxy like turbo sim, simpsons, simulator bla...bla is not total solution for unlock iphone 3G

ya sim proxy. simcard attached to that sim dummy.
is that no any solution for this problem yet .

well so far not yet. Just use it until software unlock release.
