Hi guys I'm not a noob when it comes to these things but I'm stumped on this now. I've got a a new'ish 3GS running 3.1.2, I had JB ages ago with Blackra1n but it's tethered. It's a new one so its an MC model and baseband is 5.11.07. Now I need to untether is because its driving me up the wall not being able to restart + I'm getting the whole no wireless problem. Can I update to ios4 + JB + unlock? I don't mind keeping it on 3.1.2 as long as it's unlocked and JB. Any ideas? I've looked at spirit but I can't work out what I'm doing seeing as it's already JB on 3.1.2 and I can't afford to loose the unlock.
