Unlock iOS 4.1 and 4.2: iPhone 4 not Supported?

Following on from our earlier article which informed you of Apple’s GM release of iOS 4.2, iPhone Dev Team member MuscleNerd has confirmed that a new unlock method using ultrasn0w will be available shortly after Apple’s release.

As reported from RedmondPie, MuscleNerd hinted that the new unlock will be out around 2 days after Apple release the official update to iOS 4.2.

His latest Tweet reads: ”MuscleNerd: @simplysaru if you’re on 3G or 3GS, just a day or 2 at most after 4.2 is public (just enough time to verify stuff)”

Unfortunately, this unlock method will not be available for the iPhone 4 yet as MuscleNerd stated that the updated version of ultrasn0w will only support the iPhone 3G and 3GS running iOS 4.1 and 4.2 for now.

That doesn’t rule out an unlock for the iPhone 4 completely though, you’ll just have to wait longer than 3G and 3GS owners. It is definitely good news though for 3G and 3GS users who have been waiting for an unlock even before Limera1n was released.

Let us know your thoughts on this, particularly if you have an iPhone 4.

    Hi all

    I just upgraded my iPhone 4 to a newly released firmware 4.2. YES, I somehow managed to preserve the baseband at1.59. Do you know if it is unlockable?

    Thanks all the effort from Dev-team from came the solution to JB and unlock iPhone sofar. I am a Cambodian I used to JB and unlock iPhone 3G and 3GS while my family owned a few set and it was working well on Jailbreakme and spirit. While updating firmware to latest version I still can do JB and unlock by using limera1n and ultrasn0w. However, with my iPhone 4 firmware 4.1 still can JB but cannot unlock. So how long I have to wait for ? Can any one help me?

    iphone is the best after trying one (the 3gs 16 gb) i found that it has every thing i need in a hand held device (games apps music etc…) i discoved that if you didnt get an iphone before , then you never had a phone for real.

  • Maic

    I am in Costa Rica, so there is no other way to use an iphone rater than jailbreak and unlock!! I have an iphone 4 on 4.1 from apple and sucks that looks like our unlock is the one it will take longer!!!
    Apple stuff is the best, but there policy of having everything lock sucks big time!!
