Starting with the 3GS, and all iOS versions 4.0 and above for all iDevices ... SHSH blobs are required except for the current version. 3G and 3GS users are very lucky at the moment. Apple is also authorizing iOS 4.1
Did you read the 'All About SHSH' link found in my signature?
4.1 should be relatively easy, it depends upon the current state of your computer and your iphone.
Either one incorrectly set or in an odd state will cause problems.
I will try it on a laptop with fresh stock fw 4.1 download and see what happens, if this does not work I will throw in the towel. Thanks again Mes i dont know how to do the thanks on Modmyi app, but I will later on a PC
Mes, are you sure apple did not stop signing 4.1 from 4.3.5 today? I know you are a busy man.... Hence, you are the only person helping. When u get a chance, can u read through the entire thread (anytime, you get a chance) and let me know...I have read every post here, google and other sites on this simple process... It is driving me nuts, not to mention the wife! It is just a quest to get this 3GS working without a tethered JB this is number six in the fleet of iPhones (people give me their destroyed devices and I order and replace the damaged components) and I pass them on to family and friends for free.
Thanks again Mes, you were the only person to respond to this thread at Modmyi all day.
