I loved my jailbroken iPhone4 with customised UI, fancy themes and blue backlit keyboard (I have an obsession with blue backlighting... years ago the nokia 8250 was like heaven for me!) however some b'tard who was supposed to be a 'friend' stole it. My replacement shipped with 4.2.1 software. We were promised an untethered jailbreak by Christmas but there's been little word since on that one. The new workaround or plan b requires SHSH blob files from the 4.1 firmware that obviously, I don't have. I've heard that even Comex's eventual release may require these. Furthermore I'm running a Windows PC and have no access to a Mac. Furthermore I'm a total noob at this stuff. When I jailbroke my stolen (the one stolen FROM me, I didn't steal it) it was easy. I used Limera1n and followed a YouTube tutorial. I don't understand any of the terms I'm reading and don't even know what an SHSH or blob file is or how to extract one. I'm fairly computer savvy but only on a PC running a Windows OS. Any hope or advice? Sorry if I sound stupid, if I posted out of place or if there is a thread already dealing with this. Like I said, total n00b to this.
