What is Gevey SIM Interposer?
Gevey Sim is an unlock solution for iPhone 4 with baseband 01.59.00, 02.10.04, 03.10.01, and 04.10.01 on iOS 4.x.x, and iOS 5.0. Unlike UltraSn0w, Gevey SIM is a hardware solution, a SIM interposer sits between the SIM card and the Modem to perform a classical MITM.

really helping tips you’ve to sharing. thanks
I just updated to iOS 5 my iphone 4 BB 04.10.01
It went alright, Gevey Sim unlock still working… However, i can´t use the data network of my phone. It means that I can only use Wi-fi.
Did this happend to anyone here? Does anyone know the solution?
And my phone does not recognize the contacts anymore
Which gevey r u using because I have a ultra and it doesn’t work
I’m using an Ultra as well… A managed to make everything work now.
Internet gave me a little bit more trouble, but it’s working perfectly now.
I know it’s a dumb thing to say, nut try googling your problem, and i’m sure you’ll find the answers.
If the unlock is not working, do the procedure again… It take a few tries to make it work fine (turning the phone off and on, calling 112 and etc…)
just enable data roaming and you`ll be fine
Joao Pedro Joao Pedro :
is it unthethered jail break ?
how can i Preserve iPhone 4 Baseband on windows?
They said at the top that the windows version was on the way soon. This is teathered unlock
I upgraded my iphone 4 to OS 5 without preserving the iphone 4 baseband. i now have problems with activating my iphone with the Gevey sim. Any tips of how to activate the iphone or how to downgrade it to the previous os (4.3.5)
Thank you
ouch.. theres no way yet… your stuck… gevey isnt compatible with ios5… and you cant downgrade if u havent preserved…
Any options help please. I need to restore my phone.
You can downgrade to stock iOS 4.3.5 by doing an option restore and selecting 4.3.5 firmware, apple is still signing this firmware so your baseband will downgrade also, then follow the instructions to update to iOS 5 while preserving this baseband!
Yes I did the same and got it to downgrade back to 4.3.3 so it did work. I just had to run the jailbreak for 4.3.3 again to get it to come up.
Hi djvolak,
I couldnt downgrade to either 4.3.3 or 4.3.5. I keep geting the following message: Unknown error occured (3194
Can you please advise how your solved this.
Thanks
and my gevey sim(supreme)just worked well without doing anything(i mean turning flight mode on off/dialing 112….but it does show only one signal bar… otherwise everything is working well..
because newery GEvey SIM performs these steps by itself
Hello,
I updated my i4 (BB 2.10) to iOS5 but I am not getting Gevey Sim pop message where I need to “accept.” I did not do Jailbreak by the way. Just cooked custom IPSW with redsnow (beta 6) Does anyone know why I am not getting pop message? Thank you in advance
I jailbroke it also and It did not work. I assume that Gevey Sim Ultra is not working with iOS5. Maybe I am wrong but I tried everything to make it work. So if anyone knows what I am doing wrong please please let me know.. Thank you.
You need to cut all of te plastic off of your sim card so you only have the metal remaining, then use scotch tape to hold it in the correct place on your gevey chip!
I just updated mine to iOS5 as well. I could not get the message to pop up at all. What I had to do was install “SemiTether” and reboot my phone in the semi-tether state. The Gevey pop up shows and I did the 112 process. After you get a signal, power down like normal and “just boot” with redsn0w. Worked for me at least.
Hi all,
How can I check which Gevey I have?
snowbreeze upgrades iphone 4 bb 4.10.01 to iOS 5 without change in bb with gevey sim

Hi,
I did what was mentioned but the iPhone doesn’t boot without redsn0w help, apple sign hangs for a while and then a wheel shows (frozen) and nothing happens.
Any idea why is that?
does gevey sim works with iphone 3gs ios 5 and baseband 6.15.00
hey. my iphone 4 update with new IOS and Baseband update to 04.11.08 HELP…. PLEASE
04.11.08 unlock ??
What if i have 4.11.08 ?????
There is no unlock for 4.11.08. Not even with Gevey currently.
Gevey only works with iPhone 4 currently. If you have a 3GS on 6.15.00 you can simply install ultrasn0w for unlock.
my iphone is upgrade to 04.11.08 . . is there any other way i can downgrade it? or use it with a gevey?
right now i cant you it…

Hi everyone,
I’ve an Iphone4 with 4.1 IOS and 02.10.04 bb. I’m planning to unlock it with gevey as I’ve waited a lot for the soft unlock.
I’d like to upgrade to IOS 5 but I want to know which one to do 1st?
Unlock or upgrade.
If upgrade should I need to upgrade via Itunes or any other way to make it easier for the unlock?
Pls help me!!!!!!
Pls do reply guys. I need your help.. Iphoneheat pls help me!!!!!!!!!!!!!!!!!!
don’t expect a software unlock anytime soon..
Gevey is the only solution to date to unlock the said baseband..
If you want to update to iOS 5.0.1, use a custom firmware.. RedSn0w can create one for you..
Create custom firmware with RedSn0w: http://www.iphoneheat.com/2011/12/create-custom-firmware-redsn0w/
RedSn0w CFW just preserves your baseband. You need to jailbreak later with RedSn0w..
