Anyone has any success saving SHSH blob for 6.0.1 on the iPad 4th Gen Cellular version (either CDMA or GSM). I tried TinyUmbrella but it said it is an invalid device. I tried redsn0w but it said no compatible device even when I pointed it to the right firmware. I know many people that had the iPad 4 non-cellular version without any problem. But the problem seems to be related to the cellular version that has 6.0.1 as stock. Is this true? Is there a fix?
