This may have been an resolved issue but I couldn't seem to find a clear answer. I have an ipad 2 running on 4.3.0 and it has never been upgraded to any higher versions of firmware. (which means I have not had SHSH saved other than 4.3.0) I have tried the .pdf method, but i got the 404 could not download error, seems this method is offline.. Jailbreakme.com doesn't support 4.3.0, and pwnagetool method supports only 4.3.3. Since apple has stopped signing firmwares older than 4.3.5 and 4.3.5 is currently not jailbreakable, how do I jailbreak my ipad 2 on 4.3.0? All inputs are appreciated.
