First off, you of course need an iPhone 4, but you also need a GEVEY Ultra Sim.
You'll also require the iOS 5 b1 or b2 update for your device and iOS 4.3.3 for your device.

Anyway, to start, if you're on iOS 4.3.3 you can skip to the next step, otherwise update to it if you're on a lower firmware or downgrade if you're on iOS 5. Fortunately Apple is still signing iOS 4.3.3 meaning a simple iTunes restore will do the trick.

Create a custom iOS 5 beta 2 firmware without the upgraded baseband using Sn0wbreeze. If you’ve never used this tool, follow You must login or register to view this content.. Then proceed to loading the custom .IPSW you’ve just created onto your phone.

Do not activate your phone with Apple. Instead, get around the activation process by following the below tutorial. Do not insert your GEVEY SIM at this point yet.

Triple-press the home button to activate Voice Over, then do the same thing to display an option to make an emergency call. Tap on that option.

Now when its switching for emergency call, swipe down from the top with three fingers. Guess what, the Notifications Center will show up. Now tap on the weather widget, which will start the Weather app, then press the Home button to return back to your springboard. Bam, you should now have access to your phone.

Power off your phone if you haven’t already. Then, insert your GEVEY SIM, along with the SIM card you intend to use. Keep in mind that you might have to slightly cut your SIM card in order for it to fit the iPhone’s micro-SIM slot. Make sure the GEVEY SIM is placed underneath your SIM card.

Once you’ve inserted both SIM cards, you’re ready to power your phone back on. Once it’s done booting up, wait for one signal bar to appear. Once it does, call 112. After two seconds, hang up. You don’t want to flood your town’s emergency services, do you?

Access the phone’s settings and turn on Airplane mode. Leave it on for 45 seconds and ignore all the "No SIM card installed" errors that might pop up. Once you’ve waited 45 seconds, it should be safe to turn Airplane mode back off.

And that should unlock it :y:
