If you have the saved Lockdown folder, you don't need to install SAM again. Only insert the filder with iFunbox or SSH ;)

My device:

Baseband 04.11.08

unlock solution for 04.11.08

I am waiting over 6months now for unlocking my iPhone 4 04.11.08 locked to Three Ireland network.. Its ironic, because I used SAM for sim card owned by a company I worked for. I had to give it back few days after SAM was blocked. Now I am with my locked iPhone 4 again.. How many days, weeks or months do I have to wait again??
Hackers of the world please, do find any solution for the stupid basebands 04.11.08 and 04.12.01 soon!!


I have the same baseband and it didn't work....I you finally manage to do it, please let me now =)

Vanessa Virginia Ramírez



is it unthethered jailbreak?

Jev Kormuskins

Fellas If you dont want to wait days months or years for a Unlock method just call damn ATT. If you have had or know someone that has or has had AT&T for over 2 years and your Iphone is passed the contract Then just ask them to call them and say something like my friend gave me his Iphone and I want to unlock it. They should do it no problem and then just plug it into Itunes and it should say its unloocked. Thats what i did to mine and now i have an Iphone 4 with iOS 5.1.1 that it on Tmobile


what if, if not pass the contract? i can unlock my iphone 4 bb 4.12.01?




God it did not work. My phone is Iphone 4 modem firmware 4.12.01 version 5.1.1 is there any way to unlock it?


what if my phone is locked not on ATT but on Vodafone, Orange, Three, T-mobile or anything ealse?


actually this method doesnt wornk in lock model by using absinthe. because u need to activate or hactivate it before
i tried with 3gs locked bb 6.15.00 of my frd
So the solution u need to use snowbreez and then install rocky racoon in cydia
about bb you need to install ipad baseband by redsnow
hope you enjoy


ohhhhh and then use ultrasnow as topic said that work


Hi i have unlockEd with sam on bb 4.11.08 i wanted to know how i can preseve my baseband? I have tried this with redsnow for fw5.1.1 with no luck, or can i just update to 5.1.1 with its current bb and still unlock with my backedup ticket?

Erol Ozturk

There is a way to unlock an iPhone 3GS baseband 05.16.05, without changing to a iPad baseband?


It is good for ipad bb in 3gs now
It fixed problem about gps
U need to use snowbreez to install 5.1.1
and install ipad bb by redsnow
Install rocky racoon, ultrasnow 1.2.5,and fix for 5.1.1
It works great!!!!


you need to save the activation ticket with the latest redsn0w (more->even more-> backup!)


...and then yes, you do this:

Step 1: Locate the SIM card that was used during the initial unlock process. This is the unofficial SIM card, not the SIM that was provided by the official network.
Step 2: Open up the iFile app on your iPhone and use it to navigate to the /var/root/Library directory. If you don’t have iFile installed, it is available as a package from within Cydia with a free limited feature trial.
Step 3: When you are in the directory mentioned above, select the ‘Edit‘ button in the top right hand corner of the iFile user interface. When the directory is in edit mode, select the Lockdown folder.
Step 4: With the Lockdown folder selected, press the zip button to create a compressed file backup of the Lockdown folder. Once the zip file has been created, make sure to name it something that will distinguish it and is rememberable.
Step 5: Scroll to the bottom of the current directory and make sure that your zip file has been created and is available. If it is, then delete the entire Lockdown folder using the trashcan icon.
Step 6: Bring up your Dropbox folders and locate the Lockdown folder that contains the valid activation ticket, created by the unofficial SIM card that was used during the unlock process. Open up the recently created zip file using the iFile app once again and select the ‘Unarchiver‘ option.
Step 7: The contents of the zip file will now be extracted and dumped into the default directory, which in most instances is the Documents folder.
Step 8: Once again, select ‘Edit‘ in the top right hand corner of the iFile user interface before selecting Lockdown, and press the clipboard icon which would in turn copy the Lockdown folder. Tap the ‘Done‘ button.
Step 9: Still in iFile, navigate to /var/root/Library and select ‘Edit‘. Select the clipboard icon and then tap ‘Paste‘ before tapping the ‘Done’ button.
Step 10: If you still have the SAMPrefs package installed on the device, then navigate to /User/Library/Preferences and search for SAM. When found, make sure to delete the com.bingner.sam.plist file if you can find it (it may not exist in some cases). The purpose of this is to make sure that everything goes smoothly without any conflicts.
Step 11: Turn the device off, making sure that it is powered down entirely.
Step 12: Turn the iPhone back on and wait until it loads all the way to the home screen. After the device gains a network connection, it should be with the carrier of the unofficial SIM card.

There you go!


Mode of payment please?


hi there, thanks for all the info, but im still abit confused. i had already saved my ticket with cookie and with redsnow and just to be sure "ifiled it to my dropbox account. now i want to know if i can update without being able to save my current baseband with redsnow,(cause i have tried this with no luck) and still be able to use my ticket on the current baseband that is being used for firmware 5.1.1. i am not sure what basband firmware 5.1.1 is using. if its 4.11.08 then i should be fine. cause thats the baseband i was able to unlock it with SAM. i hope this is clear. please let me know if not.. appreciate your help. thanks.


I used snowbreeze to get the custom ispw installed on the phone and then i restored it using itunes after that i installed ultrasnow fixer and then ultrasnow in that order...but it wont accept my sim carrier.. the baseband is 04.11.08...someone please tell me whats wrong..
