Unlock iPhone 4 / 4s iOS 5.1.1 with Gevey for any Baseband 4.12.01 / 4.11.08

Gevey Sim Unlock
You have just purchased your iPhone and you discover with amazement that it is locked, it shows a USB cable that requires you to connect to itunes. What you do, but itunes tells you that your sim card is not compatible ...
Too bad for you, you bought an iPhone simlock! It is quite complicated sometimes impossible to get out of this situation, but there are solutions.

First activation. Your iPhone must request permission from Apple to be enabled. Apple then check that you have the Sim operator linked to the phone and it is not blacklisted (reported stolen). Here are the options available to you:
  • You ask the seller to MicroSim linked to the phone (hopefully it works in general they use)
  • You ask a friend who uses the same operator your phone simlock lend you his Micro Sim time connecting to itunes (because you do not have to do a single time, unless you restore your iPhone) or you buy a pre-paid micro SIM good operator (even after cutting it yourself, or else from a mobile shop that often has a tool to pierce the sim).
  • You use the jailbreak "hacktivate" your iPhone. This means it is not possible on any OS, depending on the software you use to jailbreak (This is allows Snowbreeze for iOS 5.1.1).
  • You are using a PhoneBook SIM card and Universal which enables any operator but the iPhone only supports up to iOS 5.1.1.

Your iPhone is activated you can finally use it as an iPod. Now you want to call and then pick your network operator, but your sim is not the same operator a new problem appears. Indeed we must distinguish Activation and unlock.

On iPhone there are 3 types of Unlocking:

  • The Official Unlock achievable only by Apple.
However, this is your operator must apply to Apple. Legally it is not allowed by your service request the full name of the original owner, phone number, IMEI or provide an invoice. So it is very difficult to obtain a Unlock if you do not know the original owner (the majority of iPhones used). But it is still possible to negotiate, go to the base, some have succeeded.
It is allowed from 3 months after purchase, however you can get it before but it will not be free.
This requires Unlock restore the latest version of iOS and it is life. You can if you want and have the means to restore a previous version. How Unlock iPhone 5 permanent for all carrier by IMEI.
  • The Unlock software created by iPhone Dev Team.
This allows using the jailbreak software to install Ultrasnow which will then unlock your iPhone. However, not all iPhones are not necessarily compatible. Ultrasnow only supports these basebands: iPhone 3G/3GS (04/26/08, 05/11/07, 12/05/01, 05/13/04, 15/06/00 and) for iPhone 4 (1.59.00) and iPhoneS ( 04.11.08, 4.12.01 ) . It is not impossible that in the future other baseband are Unlocking, but this is not the priority of the Dev Team.
This type of Unlock is known to consume more battery problems with the GPS.
  • The material created by Unlock Gevey.us.
This is a sim card that interferes with that of our operator. It is compatible with basebands 02.10.04, 03.10.01, 04.10.01, 04.11.08, 4.12.01 and iOS 5.0.1 to 5.1.1. Your network must be compatible with national call 112 (emergency / standby) accessible at any time, which is the case in France or the usa.
The output of the new iOS 5 and baseband test is still in the world of jailbreak / Unlock, however some Gevey Sim is still supported but iOS 51.1 with basebands 02.10.04, 03.10.01, 04.10.01, 04.11.08, 4.12.01 only. Gevey III is a preparation for the new baseband.

  • Turbo Unlock tethered imposing a blank map
  • Pro: Unlock tethered
  • Unlock unthetered
  • Ultra: Unlock unthetered without having to dial 112 but with a tweak cydia.
(It is likely that there is confusion in the reference maps, the official site does not itself being very clear)

What you should know if you want to unlock your iPhone unofficially:

  • You should NEVER upgrade your baseband. During the iOS updates your baseband also gets to days as is the case with iOS 5 (or iOS 4).
  • The custom firmware is a version of the original firmware but modified, it is made by various software which Redsnow and Snowbreeze, you can customize your firmware (add a logo to boot, the battery percentage, etc ...) but also keep your original baseband. So you can switch to iOS 5.1.1 and preserve your baseband Unlocking  especially thanks to custom firmware.
  • Regardless of the method you use it is still compatible with a certain version of iOS or baseband, there is still no universal solution, always remember to ask about this before buying.
  • Ultrasnow requires that your iPhone is jailbroken, while the Gevey Sim works even without jailbreak.
  • BEWARE counterfeit Gevey sim card activation, etc ... They may work, but not necessarily correctly. In the case of Unlock example is captured less network, we often lose the Unlock unthetered is not always so ...

Concrete cases that meet most current applications:

You have your iPhone 4 unlocked unofficially and want to upgrade to iOS5:

  • For Ultrasnow (if baseband compatible) you must keep your baseband when you shift to iOS5 and jailbreak your iDevice. The Tethered jailbreak i4 current, so you need to connect your iDevice to the computer to restart. However, a tweak is output: Semi-tether (a lot of bugs) you still restart your iPhone. However you will not have access to Safari, mails or Cydia. You have to wait to find your computer to restart itself.
  • For those using the Gevey Sim. You can skip to preserving your baseband iOS compatible (as Ultrasnow), and you do not have to jailbreak your iphone. This allows you to restart without problems. Handling to use the Gevey Sim is a bit different in iOS 5.1.1 (the single bar, indicating you can dial 112 is not displayed but in fact you can still dial the call despite being written Indisp Network .). Gevey Sim Pro tested and Supreme, it works.
