I know there are quite a few threads such as this, but I don't find specifically what I need. I just want to get all my information before I upgrade to ios5. 1. Is there currently a tethered jailbreak for the ipad1 for the final release of ios5? 2. If I am unhappy with my jailbreak and ios5, is there a way to revert back to my 4.3.3 firmware with an untethered jailbreak? 3. Regarding the previous question, what exactly is a shsh blob and whatnot? I've always been lost when it comes to this subject. I do have the 4.3.3 Firmware file, is this relevant to anything in the blob context? Any helpful response is greatly appreciated. Thanks in advance!
