Apple recently seeded iOS 5 GM (Golden Master) version to developers. This is the last beta build of iOS 5 released by Apple. The iOS 5 final version will be available on October 12th to the public.
Update: GEVEY Sim Works on iOS 5 Final Version with Preserved Baseband
And, iPhone Dev Team & iH8Sn0w also updated their jailbreak tools to provide tethered jailbreak for iOS 5 GM. redsn0w 0.9.9b3 and sn0wbreeze 2.8b8 are available for download now.
sn0wbreeze lets you update to a different iOS version while preserving the baseband. Baseband preservation is needed for ultrasn0w and GEVEY sim.
A good news is that GEVEY Sim works on iOS 5 GM while preserving older baseband (04.10.01 & below). So now you can unlock iPhone 4 on iOS 5 GM using GEVEY sim.
Here are the screenshots:
Thanks to @w2no for the screenshots. He followed the regular 112 procedure to make GEVEY sim work on iOS 5 GM.

Do you have a step-by-step guide to show how to use Snowbreeze to hacktivate and preserve baseband when updating to iOS 5 ?
Thanks
I updated my iphone4 to ios this morning. the update has disbaled the gevey sim working as i am unable to go beyond the basic activation screen. how to go about that.
thanks.
Ray,
Did you use sn0wbreeze to build custom firmware or directly updated to factory iOS 5? Please follow the steps in this post.
Hi,
I upgraded to factory iOS5 a few days ago and since then the Gevey SIm has stopped working. I did not use snowbreeze. Is there a solution that is available?
Ashank, you shouldn’t have upgraded to iOS 5 directly. Unfortunately, you’re stuck with a locked iPhone & currently there’s no solution for it.
hello, i have iphone 4, baseband: 02.10.04, ios 5.0.1 and the gvevy turbo sim is really works.
i preserved my baseband by doing a custom IPSW through snowbreeze and thats all.
the only problem that i faced with her was that before i dial 112 there is no “one signal bar” i just recive a message that “no signal” and after it, i dial 112 and doing the other steps and everything works.
