I have iphone 4 unlocked version 4.0.1, I have upgraded it to 4.0.2. Is their a way to unlock it or downgrade it to 4.0.1.:ios4:
When you ha it unlocked on 4.0.1 did you let cydia save your shsh blobs? If so then you can go back to 4.0.1. As far as unlocking it when you get back to 4.0.1, im not certain
you can try using tiny umbrella, to downgrade back to the older firmware, but my experience when i was had previously used tiny umbrella, i had to change my proxy on my mac because somehow it had changed it and i couldn't contact the apple server, because it was still routing to the tiny umbrella server, so it if says apple server cannot be reached, if you choose not to use it again dont freak out lol
