Tonight I learned that the 3G does require SHSH blobs for the 4 series iOSes. Kinda explains why my Cydia homescreen states that it has the SHSH for 4.0, 4.0.1, 4.0.2, and 4.1. One time in Cydia, it asked me for permission to go get my SHSH and also said something along the lines of "You Want To Do This!" I did it at that time. But now my Cydia homescreen has no such option. Is there some other way to force a SHSH grab? (BTW TinyUmbrella simply connects to Cydia when you ask it). Basically I'm wondering why I don't have a blob yet for 4.2.1 My iPhone is currently on 4.1, and has never been on 4.2.1. Do I actually have to go through the iTunes process of putting 4.2.1 on my phone for the 4.2.1 SHSH blob to become accessible to Cydia's tentacles?
