iOS 5 is Released – iPhone 4 Gevey Turbo SIM and 3GS Unlockers Do Not Update!

(Last Updated On: June 21, 2020)

After 9 beta versions, the iOS 5 is finally released today!

UPDATE: You can now officially unlock your AT&T iPhone 4S/4/3GS/3GS.

I won’t need to go through the new features of iOS 5 as you can find them on the Apple website. What’s more important is that iPhone 4 and 3GS users who rely on an unlock should NOT update to the latest iOS 5 until a proper tool is out – sn0wbreeze for Windows, pwnage-tool for Mac or redsn0w.

MuscleNerd just announced that the latest redsn0w (to be released very soon) will have a baseband preservation mode as shown in the screenshot below:

For 3GS users, if you have the dreaded iPad baseband 6.15.00, you won’t be able to update to iOS 5 as well. Most likely you will be getting an iTunes Error 3004 and you will be stuck on recovery mode if you tried. To fix it, try either one of the solutions below:

  1. Download TinyUmbrella for Windows or Mac from here, run it and click Exit Recovery
  2. If you have the SHSH for iOS 4.3.3, download sn0wbreeze 2.7 (Windows) for iOS 4.3.3 or Pwnage tool for Mac, build a custom firmware and do a shift+restore (Windows) or Option+Restore (Mac)
  3. If you don’t have any SHSH, download sn0wbreeze 2.1 (Windows) for iOS 4.1 or Pwnage tool for Mac, build a custom firmware and do a shift+restore (Windows) or Option+Restore (Mac). Apple is still signing iOS 4.1 for 3GS (at least for now!)

Note: If you need to restore to iOS 4.x, you must install iTunes 10.4 or below.

If you are new to iPhone unlocking, all of these will be a bit too overwhelming. Relax and feel free to ask any questions below.
