Hi all, My 3GS was on 3.1.2, and I entered DFU mode after trying to upgrade to a 4.3.3 IPSW I built using PwnageTool that Retained my old baseband. However, Whenever I try restoring from within itunes to the custom 4.3.3, I get "The iPhone could not be restored. This device isn't eligible for the requested build." Is there any way I can restore so that my baseband is still unlockable? Or am I doomed to have to upgrade to the currently unjailbreakable/un-unlockable 4.3.5? (Also, This is my father's phone, and it *was* jail broken, but I'm not sure if any SSH blobs were saved. I feel like an idiot for not checking before). Thank you all in advance for any help.
