I've been reading websites and forums the whole day trying to find an answer. It seems that I cannot downgrade to 4.0.1 because of SHSH and there is no Jailbrake either for 4.0.2 and consequently no Unlock.
I have seen that i am not the only person with the same problem.
What can WE do in this case? I need to UNLOCK it to put my german SIM card!!!
Thanks for your response Annie...do you think soon we would have a solution? Do you think jailbrakeme.com would work sometime with 4.0.2? I really want to believe that...if not then we will be stuck with an iPhone 3GS working as an ipod...=(
