Hi, I have a legally unlocked 3GS currently JB'ed with OS 4.3.1 on baseband 05.16.02. As my phone is legally unlocked (paid for), do I even have to worry about what my baseband is or blobs(?) etc. to jailbreak? Can I just download stock os5 ipsw from Apple and use redsn0w to do a tethered JB? (/or wait for a untethered JB?) Thanks!
