i bought an iphone 4 via craigslist. on 4.3.5 4.10.01, first thing i did was to the tethered jb via redsn0w. i want to ditch the jailbreak, only way to do that is by restoring it. Apple no longer signs the 4.3.5 and i have no shsh blobs. i want to keep the firmware for Gevey, so im not going to ios 5. how can i restore while staying on 4.3.5. Thanks
