If you've been a reader of our blog for quite some time, then you would most definitely heard of Gevey SIM, an iPhone unlock solution in the form of a custom SIM card. A few weeks ago, we featured a new product from the manufacturers of Gevey SIM, Applenberry. The product in question is called Gevey Ultra which can unlock iPhone 4s that are running on basebands: 2.10.04, 3.10.01, 4.10.01 and 1.59.00.
Gevey SIM even works with iOS 5 beta 1, but as Apple rolled out beta 2, it seems that they somehow patched the exploit so the custom SIM card doesn't work anymore. Fortunately, the guys over at RedmondPie found a workaround that allows you to unlock your iPhone even with iOS 5 beta 2.
Before proceeding, make sure you have:
- An iPhone 4
- An iOS 5 Beta 2 IPSW which is available in Apple's iOS Dev Center. You will need a registered developers account.
- The latest version of Sn0wbreeze. Click here for instructions on how to download.
- A Gevey Ultra SIM card which you can buy at Applenberry's website.
Steps on How to Unlock the iPhone 4 on iOS 5 Beta 2 with Gevey SIM:
- First you will need to downgrade your iPhone from iOS 5 Beta 2 to iOS 4.3.3. Don't be afraid because the iOS 4.3.3 firmware is still being signed by Apple. So restoring is as simple as opening iTunes and you can restore from there. Make sure that you hold SHIFT when clicking restore so you can select the 4.3.3 IPSW. Upon successful restore, your baseband should be downgraded from 4.11.06 to 4.10.01.
- Now you will have to create a custom iOS 5 beta 2 firmware which will have a 4.10.01 baseband (required for Gevey SIM to work). We have provided a tutorial here on how to create a custom IPSW using Sn0wbreeze. After creating the custom firmware, load it into your iPhone.
- It is important that you do NOT activate your iPhone with Apple yet. Instead, use this workaround that we've provided for you earlier this week. At this point, you do NOT insert Gevey SIM to your device yet.
- Now turn OFF your iPhone. This is the time that you will insert the Gevey SIM. Place the Gevey SIM on the tray and on TOP of it is your own SIM card. Make sure that they are perfectly in place in the tray before you slide it back in.
- Once the SIM tray is properly slid back, turn ON your device. Once you are in the homescreen, wait for a few seconds until you get a signal. Once the signal bar is up, you will have to make a call to 112. Dial 112 and after 2 seconds, immediately end the call. Note that this is an emergency number and if you let the call connect, you will be calling 911 which is an illegal act.
- After placing the call, navigate to your iPhone's setting and enable Airplane mode. Wait for about 45 seconds. Take note that you will see a "No SIM card installed" error popup which you will just ignore. After 45 seconds, you can now disable Airplane Mode.
And just like that, you now have an unlocked iPhone 4 running on iOS 5 beta 2. If you encounter any errors or problems, don't hesitate to let us know in the comments.
