I found a link to download 4.1 will this work can I downgrade
not without saved 4.1 shsh saved on tiny unbrella. apple doesnt support 4.1 so you cant downgrade to it anymore. and shsh blobs are non transferable and super encripted so no work around
do tethered 4.2.1 jailbreak
these are my posts. check out the links. I got everything worked out except wireless and then the video I didn't post at the end of that string helped me get that. pm me if you have any questions.
first things first download tiny umbrella and back up your shsh blobs
