3GS (bought on release day) running iOS4, old boot rom 359.3, baseband 05.13.04. I jailbroke once last winter, but I don't think I backed up my blobs or whatever they're called. I've made a custom IPSW with Pwnage, but iTunes times out after a while when trying to restore with it. Tried redsn0w beta 5-5 but it keeps saying "unable to recognize" the IPSW. It's definitiely the correct IPSW and the latest beta of redsn0w. All I wanna do is unlock the thing so I can sell it. Thanks for any tips.
