Gevey Sim and iOS 5 Unlock

iOS 5, WWDC 2011

UPDATE: iOS 5 Beta 2 and up!

Gevey unlock (and other turbo-sims/interceptors) do not work on iOS 5 beta 2 and above, including the final iOS 5 release!

Yesterday at WWDC 2011, Apple announced (amongst many other things) iOS 5, the upcoming version of iOS that’s to be released with the iPhone 5 later this year. iOS Developers and certain tech bloggers have been given access to this build, and we’re sure one of the biggest question the hordes of iPhone users around the world are asking is: Will my Gevey-3G unlock SIM interposer work???

With iOS 5 beta (build 9A5220p), the modem firmware has been upgraded to baseband 04.11.04 and cannot be downgraded to earlier versions, meaning the only possible SIM unlock would be a turbo sim/interposer (currently either Gevey-3G or Rebel SIM); hence the worried and nervous questions going around the online iPhone community.

And the answer? A relieving yes. At least for now, for iOS 5 beta 1, it does. The process remains unchanged — just insert the interposer, restart your device, accept the welcome message, dial 112, and toggle the Airplane Mode feature a few times. The Gevey SIM will still work to unlock iOS 5.0 beta.

However, in order to install iOS 5 you’ll need (in addition to access to the iOS 5 9A5220p IPSW firmware upgrade and the iTunes 10.5b27 build) access to a real SIM from whatever manufacturer your phone originally shipped with (probably AT&T) for the activation to go through. And you’ll of course need to have your phone registered as a developer device on the iOS Developer Center website. We tested this ourselves on an AT&T iPhone 4 that was previously running 4.3.3 with the Gevey unlock.

Enjoy your interposer-unlocked iOS 5 and let us know how it goes!

  1. I have a question. So, if I have a turbo sim, do I need to install iOS 5 with the att sim card and all that or can I just upgrade it? are you sure it won’t lock the phone or something?

  2. As it says in the last section of the post, you will need an AT&T sim card to activate the iPhone. You can’t upgrade since it first does a factory reset then a sync.

  3. Activate iOS 5
    1. Triple click the home button. This will activate the Voice Over.
    2. Triple click the home button and Emergency Call will appear.
    3. Click on Emergency Call and, while it’s switching, swipe with your three fingers down.
    4. The Notification Center will appear!
    5. Click on the Weather widget. The Weather app will load.
    6. Click on the home button to exit to the iPhone’s springboard.

  4. i cant do the triple clock thing to activate voice over. voice over just doesnt pop up! does it works on iphone 4 gsm?

  5. Can you not just use RedSn0w W/o Jailbreaking the phone (for users that prefer to have a non-jailbroken iPhone) to Hacktivate the iPhone, Or does iOS 5 block Hacktivation? Please respond!:

    yes i try gevey after 5.0 upgrade and its not working”

    Me to on firmware 04.11.08!

  7. My iPhone 4 was purchased on a contract with 3G – The contract is still ongoing and active. I was prompted to use the original SIM card in order to complete the start up. I am in India now and I cannot use my Gevey (turbo) on my sim card which was working previously before upgrading to iOS5.

    I’ve tried turning it on and off – accepting the instruction for waiting 12-15 secs and dialing 112. Then turning on flight mode, turning it back off once no sim card prompt came on. Still no services after many attempt including reseting network and try the whole process all over.

    If theres any other way or solution to this, I would be glad and deeply appreciate your assistance.

    Many Thanks.

  11. Take a look at this video This guy proves that gevey sim does work on iOS 5. He made this video on the day the iOS was released. Please do give your feedback whether it works for any of you or not.

  12. Ajmal, your technique does not work for normal upgrades. One must use a custom (hacked) upgrade to preserve baseband for that to work.

    Once one has upgraded normally/automatically to iOS 5, this method cannot be used and the previous baseband cannot be restored.
