Unlock iphone 3gs 6.1.2 [ 06.15.00 ]

Hello coupe of things here to talk about:

1) did you previously have Cydia installed on your device?
if you did it seems to me that you have i unlocked by ultrasnow

2) Do you have Cydia installed now?
if you do have Cydia installed you can try to add the ultrasnow unlock and the ultrasnow fixer i can see that your are on the ipad baseband so its worth the try ....

Let me know how it goes...

I've already tried it, with Ultrasn0w and Ultrasn0w fixer for 6.1, unfortunately it doesn't work

I just managed to work things right for same model and firmware update:
Follow these steps:
1.Restore your iphone 3gs with itunes to 6.1.2
2.Use redsnow 0.9.15b3 to jailbreak ==> Extras===> Select ISPW====>Select===> Restore.ispw====> Select OK===> Back====>Jailbreak====> Only select insyall ipad baseband and NOT cydia.
3. After Completion your iphone will be activated. Wait more steps.
4. Download Evasi0n and run the tool with your iphone 3gs attached.
5. Dont do anything and let it again jailbreak 6.1.2
6. Once Done you would get Cydia on the homepage.
7. Open cydia and install source: repo666.ultrasn0w.com
8. Install ultrasn0w on iphone 3gs from cydia.
9. Your iphone 3gs is unlocked and any sim is activated.
10. Do a network setting reset again later for steady Network.
11. Done Cheers!

Hi, I also have the same issue and I tried to use redsnow but it says the ipsw version is unsupported. Any more ideas?

If your iPhone 3GS's baseband were 06.15.00 downgrade your baseband to 05.13.04 using redsn0w's "downgrade from iPad's baseband" then install ultrasn0w using Cydia.

Thanks! Gave it a try but My issue is the latest version of redsnow isn't accepting any ios 6 Ipsw version. Tried 6.0.1, 6.1, 6.1.1, 6.1.2 and none of them worked. Which do I use?

"github.com/iH8sn0w/sn0wbreezedl/archive/master.zip" this link is sn0wbreeze 2.9.11 and use this jailbreak tool if you cannot use sn0wbreeze watch videos from youtube. Goodluck.

Hi there, I have exactly the same as your problem, I updated 3GS BB 06 .15.00 from IOS 4.1 to 6.1.2 using sn0wbreez 2.9.11, i thought it's factory unlocked but no Service,
I tried to reinstall mobile substrate and ultrasn0w to unlock but no luck, I think now I just have to pay around 100$, to unlock this Canadian 3GS ,

Any other thoughts ? Because I googled for hours now with no luck...!

Could be a little intimidating to speak with Jon Robin some people may compare it’s at you and if it's Harry in conference people make compared to let's begin with the Pope a Catholic Conference or something hot and yet for me it also feels like being very at home because I my dad before he wrote diet for a new America hi he was the same man he is today which is a human being trying to live his conscience his values as best he could in this world and hopefully to be able to share whatever he learns with others along the way and to grow up in the harm in which grew up in which we had dinner time conversations about things like the state of our world and our dreams and our prayers and while we were struggling and what we were hoping to accomplish not just in our own personal lives but for this planet we talked about war and peace when I was about 7 we were talking about us what we can learn from the history of violence that humanity has endured and how we could create a future that was different than that history when I was about to eat and I organized peace rally in my elementary school we were talking about food choices so I started a natural.
