I've been trying to jailbreak my iPhone 4 (GSM) running 6.0.1 constantly, but am unable to do so for reasons that I cannot fathom. Using the latest version of redsn0w, I go through all the steps, using the 6.0.0 IPSW for my iPhone 4 GSM, and so on. All the kernel boot stuff comes up on the screen, then the running pineapple appears and installs the basics, as usual. Redsn0w claims success, phone reboots, and bam: no Cydia, seemingly no jailbreak. Very frustrating. Yes, I did select "install Cydia". I then (re)boot tethered, pineapple pops up again, everything seems to go according to plan but again, no cigar. My phone just won't jailbreak, and there aren't even any errors to grapple with! Most frustrating. I have been jailbreaking my phone since I got it, and I've never had such a weird problem. Has anyone had the same/know how to help?
