Downgrade iOS 4.1 On iPhone 3G/3GS And iPod Touch 2G/3G To 3.1.3 Without SHSH Blobs

We have seen couple of guides circling the web which “claimed” downgrade from iOS 4.x to previous OS versions like 3.1.2 and 3.1.3 on iPhone 3G/3GS and iPod Touch 2G/3G. However, those guides had a very minute success ratio and iPhone developers and hackers from Dev Team also indicated them as non-workable without blobs saved. Today I stumbled across a downgrade video guide on YouTube that allows you to downgrade your iPhone 3G/3GS and iPod Touch 2G/3G to iOS 3.1.3 without having the need of your saved SHSH blobs. I also had a little conversation with video up-loader and he claimed the guide as working for iPod 2G/3G in particular and any 2nd or 3rd generation iDevice in general.


Here is the guide to downgrade your iPhone 3G/3GS and iPod Touch 2G/3G without saving SHSH blobs as per the video on Youtube. We do not guarantee if it will work, but you can try this and let us know. 

  1. Download Sn0wBreeze Ver 2.0.2 along with iOS 3.1.3 and save them on your desktop [ Or wherever your prefer].
