Well, MuscleNerd has reported earlier that he had been working on an iPhone 4S unlock. Till the time he would be able to achieve the target, he wants us to keep certain things in mind. These are some of the tips for people desperately looking for an iPhone 4S software unlock in the future. First of all, you should be on the least firmware pushed to iPhone 4S. In other words, lowest BaseBand possible.
We all know that iPhone 4S comes with iOS 5.0 pre-installed in the device. And there are two new iPhone 4S firmwares available. One is iOS 5.0.1 (9A405) and another one is iOS 5.0.1 (9A406). Unfortunately, if you have updated to any of the firmware, you couldn’t revert back to iOS 5.0 through any way right now. However, if you are on build 9A406 of iOS 5.0.1, you can revert back to 9A405 until iOS 5.1 is released from Apple. So, we would advise you to try to be on the lowest firmware even if it is in the case of build number.
There are pretty high chances that the iOS 5.0 or iOS 5.0.1 (9A405) is more vulnerable to the exploit which would be used to unlock iPhone 4S. Also, save SHSH Blobs using TinyUmbrella or Redsn0w which would allow you to revert back soon. However, the baseband can’t be downgraded once it has been upgraded manually in iTunes. Though the firmware could be downgraded with the help of saved SHSH Blobs. These are some of the things which you should keep in mind if you are planning for software unlock of iPhone 4S.
The JailBreak for iPhone 4S could be released in few days. But there’s no work going on for iPhone 4 unlock. Nevertheless, the effort to find baseband crashes is still going on. Let’s know what do you think about it in the comment section.
