    I searched forums, found quite a lot of unrelated topics, neither one has helped me. Sorry if solution is trivial :|

    I'm trying to restore my 3GS iPhone (with original 4.0 on it) to custom 4.1 IPSW. I checked available SHSHs with TinyUmbrella that 4.1 is an option for me. However I get error 1601 when trying to restore prepared IPSW in DFU mode. I've read here somewhere, that inserted SIM might have some effect on this, so I removed it, tried again and got 1600. Is it symptomatic? Any ideas?

    In case anyone wonders. I re-downloaded, re-built IPSW, turned off TinyUmbrella and it magicly restored!.. So I got it Jailbroken and Unlocked now. Thank you guys for your tremendous work and efforts to keep it alive.
