    Question can i update my iphone 3g to 4.0 right now? Or is it impossilbe since the newest firmware is 4.1. My iphone has never been jailbroken so no shsh blobs. At this moment my 3g is on 3.1.3 but it is on a endless boot logo loop so I can't even get to the freaking homescreen so i have to restore. I am guessing I can't just restore to 3.1.3 right?

    You can restore to ANY firmware with the older bootrom by just using DFU mode + shift-click restore.

    I think you need SHSH blobs so I think you have to go with 4.1. If its the jailbreak there should be one soon but 4.1 is cleaner and faster

    actually you can just restore to 3.1.3. But if you want to, go ahead and restore to 4.0

    iPhone 3G doesn't have SHSH checks

    Yes it does.

    It has a soft SHSH check for firmware 4.0+.
