Ok, so I think I'm pretty knowledgeable the whole jailbreak thing (I said I think I am). Anyway, I do get confused on a point. Everything I read is that TU saves your SHSH and allowed me to update while preserving my baseband. I'm have an iP4 with fw 4.1 and bb 1.59.00. So I guess my confusion stems from pwnage tool preserving the baseband. Doesn't TU do this? Or does it all depend on which jailbreak tool I use?
