Cydia has saved my iPhone's SHSH from 3.1->4.1. Why isn't it saving 4.2.1? I see that the dev-team will release a JB that will require 4.2b3 SHSH. Am i missing something? Cause i thought Cydia will save SHSH automatically once i choose "make my life easier". What's 4.2b3? Wouldn't it be 4.2.2 or 4.3,etc?
