I have an iPhone 4S on IOS 5.1.1. it's AT&T and i'm using a gevey S Ultra to unlock it. Is there a way to update to IOS 6 GM and then go back to ios 5.1.1. the same way it was before, same baseband etc?
Got a tip for us?

Stop jumping to the latest thing then come back crying for help. It's only a week before the official release.
It won't make a difference when the official IOS 6 is released... I would still have the same question but without the 'GM'.

I thought GM doesn't need that.

Do those "unlock my iPhone" sites really work? If so, you just provide them with the imei number and that's it?

I'm not clued up on the baseband issues, but I wish people who don't have a damn clue would stop spouting inaccurate information regarding downgrading from either beta or GM versions of iOS.
I know the "official Apple notes" in both the beta and GM versions state you cannot downgrade, but they are wrong.
Any iOS device will restore to the latest public build of iOS. This means, until 19th Sept when iOS 6 is released, that 5.1.1 is the latest (and in the case of recent iDevices, the only) build of iOS that is being signed. When iOS 6 launches, 5.1.1 will stop being signed and then you won't be able to downgrade unless you built a custom ipsw using stitched blobs (for example).
The above is from personal experience.
Betas were downgrade-able by entering DFU mode and shift+restoring. I tried every beta of iOS 6 then went back to 5.1.1, and if I tried a basic sync + restore it told me my device wasn't eligable for the requested build and this meant I had to use DFU mode.
The GM, providing you have 5.1.1 saved in your iTunes software folder, will restore using a basic sync + restore.

Why don't you wait for the official release? Does it make you THAT cool to have iOS 6 a week before the public?
I'm the only one that will know and see that my iPhone has IOS 6 on it, but yes it makes me that cool.
As I understand I can update to IOS 6 now and go back to IOS 5, but when IOS 6 is officially released I will not be able to go back to IOS 5. That is also why.

yes you will be a very 😎 guy for 4 days! 🙄 hope it doesn't mess up your Gevey check with people using GM see what baseband it is or check with Appleberry. I never install IOS beta's. I'm probably looking at a month or 2 before or until the jb is out before I even upgrade IOS 6.

Limera1n is a hardware based exploit for i4 5 and 3gs you will have a tethered jailbreak very shortly for those devices there are things that still might take a few days but the wait will not be long. untethered and A5 is a whole other story time will answer that.

Thanks for the info. Tethered JB is useless to me, so I guess I'll have to wait for the unthethered release. Hopefully it will be sooner rather than later.
