As the title says, I have a jailbroken iPad on 3.2 and am wanting to upgrade to 4.2.1; obviously still jailbroken.
My question is, is there a jailbreak upgrade process which googling and searching this forum hasn't revealed? Or do I just upgrade and then jailbreak again?
I don't have SHSH blobs saved for iOS 4.2 Beta 3, and I'm assuming these aren't downloadable as they're generated and hence unique, by your own device?
That redsnow will not work for you since you dont have the required SHSH. The only option for you is what Yeow said before using redsnow 0.9.6rc8 for a tethered jailbreak.
