I have a iPhone 4 running 4.1 with baseband 02.10.04, with SHSH saved for 4.1. I tried Pwnage 4.1.2 the other day, which is supposed to provide a untethered jaibreak for iPhone 4 on 4.1 But after (repeatedly) creating the custom IPSW, when I try the restore in iTunes I get the error message about my device not being eligible for the requested build. Is this because Apple is no longer signing 4.1? If so, is all I need to do is edit my host file to point to Saurik? Thanks!
