Have a 3GS jailboken & unlocked with pwnagetool/redsnow on ipad 06.15 .00 firmware.
How do i upgrade to the untethered JB and keep my unlock ?

Just run Greenpois0n over it and you will have an untethered jailbreak.

Ok ran greenpoison over it and have an untethered JB but have lost my unlock.
Have tried reinstalling ultrasnow a few times, power off/on, sim in/out, ect but no luck ?
Please help me get my unlock back, anyone ?
Thanks

Greenpois0n has nothing to do with the problem you have now. Which network carrier do you have?

I'm with Vodafone in Australia, phone is locked to Optus.
Thanks

Did you try reset network setting as well as hard reset?

 

[acpowman]
