Party is over folks, if you're using a Gevey turbo sim to unlock your iphone 4 dont update to any of the betas.

Apple has blocked the ability to unlock the iPhone 4 using the Gevey SIM in iOS 5.0b2, according to MuscleNerd.

it's surprising Apple closed Gevey interposer hole in b2 rather than waiting until final (maybe they were under pressure)

Gevey's SIM Interposer was able to unlock the iPhone 4 by force activating the baseband using the emergency dialer. MuscleNerd notes that its unlikely Gevey will try to battle Apple while iOS 5 is in the beta period.
 
not sure how major IOS updates are with older basebands, but can you possible preserve IOS 4.3.3 or even IOS 5 Beta 1's baseband using TinyUmbrella when updating to IOS 5 and still be able to unlock the phone?

Interesting question, does iOS beta 2 update the baseband from beta 1? If it doesn't then u can't preserve it.

That's what I was thinking too.
I wonder if you save your BB with TU if the gevey will still work. We gotta wait and see I guess.
In the meantime those that need to stay unlocked using gevey stay away from betas and ios 5.0
 
Wow, this makes me wish that home phones were service locked to the provider, that way when you moved, you couldn't take your home phone with you and use it on another carrier.
 
Not surprised, really. Meanwhile, I still have to roam again in august, so perhaps I'll use the Ultra, or just use my iphone 3GS which is unlocked. Then buy an unlocked iphone next round.
Thanks for the heads up.

Ill be curious if the folks who unlocked via the various white list services will find themselves re-locked...

i tried this for fun but... updated to ios 5 beta 2 and the baseband is 4.11.06 i believe... and then i downgraded back to 4.3.3 with the 4.10.00 or (w/e) baseband. i hope they find a way to preserve the baseband when 5.0 comes out haha
 
Wow that sucks, It means now that if I would like to upgrade to iOS 5 it means I will have to spend another $40 For a newer Gevey. I just hope applenberry will find a solution for iOS 5 Instead of nothing.

We dont even know if there will be a new gevey that will be able to hardware unlock past 5.0 though.
 
I wonder if the rebel sim is affected. I'm running the rebel right now on firmware v5. Hopefully rebel will post something or a new firmware.

I don't think so. The white list was similar to a "Factory Unlock" so I don't think they would ban specific IMEI numbers through a firmware upgrade. If they wanted to do that, they would have gone in manually and disabled/kicked them/whatever.
