    I've tried to install iOS 4.3.1 on my iPhone 3GS. Then I downgraded it to iOS 4.2.1 coz 4.3.1 was not being signed and I think I dont have it's SHSH blobs saved. So, after downgrading to 4.2.1, I jailbreaked it with redsn0w. After the jailbreaking process, it is asking me to insert a vaild SIM to activate it which I dont have. I even tried to jailbreak it with Greenp0ison but it shows me the same error. It was working fine earlier on 4.2.1. Plz help me guyz, thanks.

    Buy a sim, that the phone is locked to, off ebay. It doesn't have to be active, it just has to be the correct SIM.
    Either that or use pwnage or another jb software that hacktivates.
