I was on 4.1 jailbroken with sn0wbreeze and I wanted to install android on my iphone. It said it was only possible with redsn0w. So i did a fresh restore of 4.1 and tried to jailbreak with it. It keeps on getting stuck on the uploading ramdisk part. I have an iphone 3rd gen 8gb, running 4.1 like I said. please help, thanks.
