I have been trying for a few days to Update my Jailbroken(redsn0w) iPhone 4(Verizon) 4.2.8 to a higher Jailbroken iOS no matter which iTunes version I try, how I edit my host file, using sn0wBreeze(doesn't work because of host issues), using redsn0w, or anything else I try wont work. I was considering restoring my iOS back to OEM, but I'm unsure if I will be able to upgrade the iOS and jailbreak it again, because I ran into this issue when I initially tried to jailbreak it. Anyone have any suggestions
