108 Comments to Unlock iPhone 4 Baseband 4.11.08/4.12.01 On iOS 5.1.1 Using Activation Tickets With Redsnow (Guide)

  1. Yet MORE BS about 4.11.08 Why don’t these HACKERS ADMIT Apple has beaten them and that’s why they are not working there!!

  2. i read a comment where a guy said he had his iphone with bb 4.12 unlocked by the retailer who sold the phone for him for just 120 bucks. the best way any one can possibly unlock your iphone4 with the dreaded 4.11 or 4.1201 bb is to give it to those who are specialized in factory unlocking of iphones in your locality or do it online with your imei number. Its simple, all they are going to do is do a total factory unlock for you, its gonna take just couple of days and your iphone will be unlocked officially by the carrier forever. one thing you all are failing to understand if factory unlocking of the iphone doesnt matter what bb you might be on, it works for all bb. the reason why people keep asking for the unlock of the bb 4.11 and 12 is because they dont wanna spend money fixing it, they want it for free. if you have the money you will have your phone factory unlocked. 100 to 150 dollars could do that pretty good. i advise you all to stop wasting your time waiting for an unlock solution and focus more on finding some one who does factory unlocking where you live and pay for this crap.

      @Elvis Is there any online service to factory unlock that is reliable. If so please kindly let me know. There are so many advertisers on the web but its wise to get someones opinion before i throw my arms into it. Thanks in advance.

  3. well it didn’t work. says here they couldn’t find any activation tickets even though i’ve already backed that up.

  4. AT&T will NOT factory inlock your phone if it is still under contract. NO MATTER HOW MUCH YOU PAY.

    • Dear Sir: I could factory unlock any AT&T iPhone. Yes, even if it’s still under contract..
      Interested persons may contact me at agag207@me.com use the words iPhone – Unlock in subject line.
      I can get it done in 2-4 days.

  5. …yes I think Elvis is to the point. I want just to add that not all the providers from all countries are unlockable.
    I found a shop in my country that providing this service but when they checked that my iPhone
    Is under t-mobile Hungary they said to me not supported from they server.

  6. how many years is this unlock ticket is valid 3 years??? and can i put this ticket in my other iPhone and put the same sim and use it???

  7. @rizmycool it best you find some one in your locality where you live who can do this factory unlock for you or if you have a friend in the U.S who has an at&t account, they can help you If yours is locked to AT&T. you will also be lucky because it is definite you will get it unlocked. because most cases of iphone that has been successfully factory unlocked are locked to AT&T network. mine was AT&T locked, and i’ll be going over in two days time to collect it. a friend of mine got his unlocked few days ago as well bb 4.11 AT&T locked. if you are just a user and not an hacker or a developer of these iphone jailbreaking softwares and stuff, i suggest you go for a factory unlocking or a factory unlocked iphone or else you are not going to have a full rest of mind using something you bought with your hard earned money. but if you are not lucky enough to have the service provider which your ihpone is locked to available for unlocking, i strongly suggest you sell it and buy a factory unlocked one.

  8. and talking about your phone needs to be off contract before they can unlock.. its is not certain, as there are still those that unlocks iphones even while still under contract. if im not mistaking the iphone4 was released by June 24, 2010 and most likely so many signed up for 2 years contract with the AT&T network on their iphone4. judging from the time, the iphone4 has existed, there are still so many users of which i am a living proof has had their iphone4 AT&T locked unlocked. of which i am very sure its still under contract. so, i strongly suggest, you take your phone to those who can do the factory unlocking and see if they can unlock it and that will depend on the service provider which the phone is locked on to. go and and try your luck. or still you can wait for these hackers to find a solution, maybe that’ll take couple of weeks, months or maybe till the iphone5 is out. we cant tell.

    Hi guys can I have some help please i have a 5.1.1 bb 04.12.01…while going to tickets i received this message
    “Sorry the device isn’t currently running the “afc2″ service required for this function. Please jailbreak and install afc2.”

    I do apologize for my ignorance how in the world i jailbreak this thing?
    Thnak you so much!

  10. I don’t even have to do these steps. I used NO_BB…ipsw and it unlocks itself after the restore and jailbreak. I guess is choose NO_BB… ipsw then the ticket will not be over-ridden and it stays on the hard disk on the iphone.

  11. Can any1 post how to update to iOS 5.1.1 using the pwnage thing I don’t know how to update

  12. Can someone share their tickets plz? I really need to unlock this phone, sure we can all go factory unlock, the point is, its a rip off to pay 150 for a unlock, its a way of making money out of nothing. If someone could share tickets i would greatly appreciate. Thanks

  13. i dont have the ticket can anyone upload his ticket file for iphone 4 gsm……… i wnna unlock my iphone 4

  14. I am trying to follow the process as mentioned however do not get Tickets field highlighted, its greyed out. Please let me know the complete procedure in detail. I need to unlock my ATT 4.12.01 Iphone 4

  15. This is awesome guys. Some days ago I posted a thread on this blog that AT&T wasn’t willing to unlock my IN CONTRCT iPhone which I bought off a guy on eBay even though he upgraded to the iPhone 4S with AT&T. I spent like 2 weeks trying to get my iPhone unlocked with no luck..
    Now I  learned the ropes got the right contacts and got my in contract iPhone unlocked in 24 hours. If you need help I can help you out, it doesn’t matter which model or make or baseband.  (even 4.12.01 can be unlocked)
    One restrictions applies –> it cannot be reported lost or stolen.
    If your iPhone was reported lost or stolen forget about it. It won’t be unlocked for no money in the world. Otherwise, your in luck. Sucess rate is nearly 100% with 1-4 days waiting time. Usually less than 2 days.
    If you need help please contact me through email agag207@me.com use the words iPhone Unlock in the subject please. I will only accept 5-6 unlocks per day as the method could be abused.

  19. I want to know if i follow these steps, will it work on iphone4 baseband 4.11.08 ios 5.0.1?

    Someone get on to me please if they’ve tried it

  20. Hi guys,
    I have an IPhone 4 (IOS 5.0) on 4.11.08. My problem is:
    a) I can’t seem to jailbreak it unetethered. I have tried Redsn0w and it is working in a tethered state.
    b) Considering that I have not used SAM before and don’t possess any activation tickets, Is there any way for me to jailbreak and unlock it? Thanks. Saq

  21. Is there any chance that a SAM unlock has become a permanent factory unlock in Apple record of my IMEI number? I have not tested it using another SIM card yet. Just like to know why on IMEI record my iphone is considered factory unlocked!

    Hello guys!! I have already bought a iPhone from Austria and now I am in Greece! (iPhone 4 5.1.1 on 04.12.01)
    I am searching how to unlock the sim .. I already jailbreak with absinthe and downloaded SAM but nothing happens, also from tutorials.. I don’t know if I am doing something wrong I am not and the most expert person.. Is sam working on this iPhone?
    Your help is my iPhone… so please if someone got my answers pleaseee!!!
    Thanks a lot! :)

    • As far as Sam is concerned, to what i know, it doesn’t work on any baseband anymore as Apple has blocked the servers.

    • And Yes, SAM WILL ONLY WORK if you have saved the previous activation tickets that were obtained when you unlocked your iPhone earlier (when SAM used to work). If you have done so, theres a procedure to use the OLD activation tickets again when unlocking the new baseband with SAM.

  23. Dear Sir: I could factory unlock any AT&T iPhone. Yes, even if it’s still under contract..
    Interested persons may contact me at agag207@me.com use the words iPhone – Unlock in subject line.
    I can get it done in 2-4 days.

  26. Hey Guys,

    I accidentally upgraded to IOS 5 without thinking. I had a gevey sim card using T-Mobile on an AT&T Phone.
    After the upgrade, the phone went back to being “unactivated”. I have 4.12.01. I just want it to work with T-Mobile again. Can I just use a AT&T sim card to activate the phone again? Or do I have to something else. Would highly appreciate any help I can get. Thanks!

    ALL IPHONE UNLOCKING JAILBREAK ANY VIRSON
    IPHONE 2G,3G,3GS,4,4S,
    IPAD 1,2,3,

  40. Quick Question: I want to upgrade to 5.1.1 so I can have an untethered jailbreak. Currently on 5.1 w/ 4.12.01 bb with SAM unlocked AND I have my backup zip file for SAM.
    Should I use iTunes to do the upgrade to 5.1.1 (after I back-up using iTunes?
    Thanks

  41. So…I updated to 5.1.1 using iTunes. The phone is not jailbroken now BUT it is still unlocked (previously unlocked using SAM).
    I will now jailbreak using redsnOw 0.9.12b1 and hopefully it will still be unlocked.

  42. I was locked on 5.1 bb 4.11.08 for months. I used a very simple thing to unlock it : everyday checking for an update, and 1 day SAM popped out… So now I am unlocked and you’r not. Keep it up losers! :D
