    • 2 questions:
      – pretty sure I hit “make my life easier” so my SHSH is on Cydia’s server. If I didn’t, what will happen if I try this? Will it just not work and I’ll still be on 4.0.2?

      – I can’t seem to replace that host file, its says I don’t have permission or something.

    • What do you mean by “who have saved SHSH to the Cydia Server.”
      I’m trying to downgrade my iphone to jailbreak it but I’m having trouble.

    • Hello there,

      I need information about the downgrade.
      I currently have iphone 3G with 4.0.1.
      I plan to buy iphone 4 (maybe will have unfortunately 4.0.2).
      If i save SHSH of my iphone 3G 4.0.1, may i downgrade iphone 4 in 4.0.1??? And then jailbreak it and unlock it?

      Thanks a lot for your help ;-)

    • what if there is no “hosts file” in the etc folder?

    • I was able to downgrade my iPhone 3GS from 4.0.2 to 4.0.1 WITHOUT SHSH blobs. I followed the following instructions:
      http://www.iphone-network.net/downgrade-your-3gs-from-4-0-2-to-4-0-without-having-your-shshs/

      The trick is to get iTunes to think it’s installing 4.0.2 when really it’s installing 4.0.1. The process is quite trivial. All you really need is winrar and a copy of the 4.0.2 and 4.0.1 firmware. The firmwares are easy to get just google “iPhone firmware” and it’ll be the first link.

      With a little tweaking these instructions worked like a charm. I just jailbroke and unlock the phone using jailbreakme and ultrasnow.

      Good luck.
