I would like to update to iOS5, jailbreak (untethered), and eventually unlock. My 3Gs has the old bootrom, so I understand that an untethered jailbreak is possible. I don't need to unlock right away, so I am willing to wait for the unlock. Should I just first update to iOS5 through itunes? Is it correct that this will also update to a new baseband which can eventually be unlocked? Then can I follow the instructions on iClarified using RedSnOw to jailbreak (untethered) without updating the baseband?
