I've been searching for a while (with no avail) but I figured I might as well ask here... I'm trying to upgrade my roommate's 3GS to 4.0.1. It's currently jailbroken/unlocked on 3.1.3 has the new bootrom [iBoot-359.3.2] with baseband 05.12.01. Cydia shows SHSHs for iOS4, 4.0.1, 4.0.2. What are my options, if any? Thanks!
