Unlock iPhone 4S (GSM) on iOS 6 Using New GEVEY Ultra S

When it comes to unlocking the iPhone so it can be used for just about any other carrier, you can either do it by installing Ultrasn0w, or by using an interposer SIM such as ApplenBerry's Gevey. With the release of iOS 6, unlockers are left with no choice but to hold off that upgrade because their unlock solution will most likely not work with the latest firmware. The hardware modders over at ApplenBerry are apparently hard at work to make their Gevey SIM unlock solution work with iOS 6. Now, we are glad to inform you that ApplenBerry has just recently released GEVEY Ultra S that unlocks the GSM iPhone 4S with iOS 6.0, but there is a catch.

Gevey Ultra S Unlock iOS 6
That's right, iPhone 4S users who are running iOS 6.0 build 10A403 can now remove the carrier restriction on their device using GEVEY Ultra S. In case you don't know, GEVEY SIMs are plug and play unlock solutions for the iPhone, which means you don't even need to be jailbroken in order to take advantage of them.

GEVEY Ultra S Features:

  • True Plug-and-Play Unlock with no Jailbreak required
  • Unlocks GSM iPhone 4S running iOS 5.1 to iOS 6.0. (iOS5.0 & 5.0.1 is Not Supported)
  • iPhone 4S requires upgrading to the latest firmware 6.0 to get unlock
  • Works with Modem Firmware 1.0.14, 2.0.10, 2.0.12 and 3.0.04
  • Works with all iPhone 4S SIM Cards, including FIDO, Germany T-mobile and other carriers with special SIM cards
  • No SIM Card Cutting or Physical Modifications
  • No Need to Dial International Emergency Number 112
  • Low Power Consumption
  • Custom SIM Tray Included
  • 30 Day Satisfaction Guarantee

Gevey Ultra S for iOS 6

GEVEY Ultra S Supported Basebands:

This current version of GEVEY Ultra S for iOS 6 supports the unlocking of iPhone 4S running on iOS 5.1 (build 9B176 ) with baseband 2.0.10, for iOS 5.1.1 (build 9B206) with baseband 2.0.12, and finally iOS 6.0 (build 10A403) with baseband 3.0.04. NOTE: Firmware iOS 5.0 and iOS 5.0.1 are NOT supported.

We have previously mentioned that there is a catch to using GEVEY Ultra S, and it has something to do with MMS functionality. According to the product page of GEVEY Ultra S:

The GEVEY™ Ultra S for iPhone 4S iOS 6.0 does not fully support MMS functionality in GSM iPhones. Due to the way MMS settings are locked within iOS 6.0, there are limitations on manually inputted settings. iFunBot, iBackUpBot, and Jailbreak have been used in previous iOS versions to manually program SMS and MMS settings and circumvent this issue. cannot guarantee a solution will be made available for this issue with the GEVEY™ Ultra S for iPhone 4S iOS 6.0.

GEVEY Ultra S for GSM iPhone 4S is now available via ApplenBerry's website for $22.99. ApplenBerry has a pretty good track record with their GEVEY products but still we would recommend that you wait for more positive reviews before shelling out for this GEVEY Ultra S.

    #Raqueliait is hard-coded into the phone for the carrier, so no one can unlock it permanently but the carrier them self.

    Can someone exiapln why this or jailbreaking and going back to a different baseband is necessary to unlock an iPhone. I ask because my girlfriend bought an unlocked iPhone 4 in Hong Kong last year. Looking at her phone, it uses the same ipsw file as a locked phone. Because it uses the same ipsw it seems like there can’t be any major differences between a locked and unlocked phone, so why is it so hard to unlock an iPhone. Is there a hardware difference or is there some sort of firmware that isn’t updated with an OS update. If its not a hardware difference why is it so hard to port the firmware from an unlocked phone to a locked one?
