How to Unlock iPhone 4 Using Gevey SIM on iOS 5.1.1 [Guide]

Unlock iPhone 4 with Gevey SIM

Hi there folks! Today we have a guide for you to unlock iPhone 4 on iOS 5.1.1 using Gevey SIM. But before you proceed, let me remind you how important it is to preserve your old baseband.

The baseband that is eligible for unlock should be protected with all your effort as losing it would mean you can't unlock your iPhone. iTunes can update your baseband while updating to iOS 5.1.1.

Ultrasn0w 1.2.7 can unlock older basebands on iOS 5.1.1. However here the basebands which can be unlocked via Gevey:

  • Baseband 02.10.01
  • Baseband 03.10.01
  • Baseband 04.10.01

Guide to unlock iPhone 4 iOS 5.1.1 using Gevey sim

Step 1: Do a full restore, after that, eject the SIM card from the iPhone and reboot it.

Step 2: Switch off the Cellular data and 3G.To do this, go to Settings > General > Network.

Step 3: Insert Gevey sim and sim card together in your iPhone 4.

Step 4: Now the accept screen will appear. Tap on Accept.

Step 5: Now you are likely to see No Service. Don't worry! Wait for 15-20 seconds and dial 112 and hang up after a couple of seconds.

Step 6: Turn on the Airplay Mode and wait till you see the No SIM card installed message! Now turn off the Airplay mode. No SIM Failure would appear. Press Ok and the iPhone should be connected to the network.

Easy isn't it? If you follow this tutorial correctly, the iPhone 4 would be unlocked on iOS 5.1.1 using Gevey. Those with GSM & CDMA iPhone 4S can use Gevey Ultra S for basebands up to 2.0.12 to unlock their iPhones. Feel free to comment below!

hklt0110

they forgot the 4.11.08/4.12.01 -> end of their greatness..They will never ever crack the 4.11.08/4.12.01, or if they even get a slight/glimpse of codes that can be crack, they will sell it to Apple . We are talking here about money people, not greatness..

I have an iPhone 4 with iOS 5.1.1 but the bad news for me is that it has baseband 04.12.01 which means that Gevey isn't working for my iPhoen anymore. I've tried dozens of "solutions" but none worked... is there a way to go back to baseband 4.10?

Pascal Eugene

thanks dude ! worked ! <3

Jibril

it worked for me , great your site , have good luck

DawgZilla

Nope. You can't downgrade basebands. Your only bet is to factory unlock it. You can find cheap chinese stores that do it for 50-60ish bucks.
