Unlock iPhone 4 iOS 4 with ultrasn0w or limesn0w

iPhone 4, the much awaited product from Apple has been officially announced. The wait is not over yet becuase it will be available for public on June 24 2010. As usual in USA, iPhone 4 will be available with 2 years AT&T contract. What if anyone wants to use it on some other carrier like Verizon or Tmobile?  There are two options for customers willing to use iPhone 4 on any carrier around the world. First option is to buy factory unlocked iPhone 4. The second choice is to unlock iPhone 4 using a tool developed by Hackers.

There is no potential harm in unlocking iPhone 4 except it may void Apple’s warranty. We have already discussed iPhone 4 unlock in some detail. In this article, we will discuss unlocking iPhone 4 on iOS 4. An unlock is actually manipulation of firmware (Baseband) running on iPhone. iPhone should be already jailbroken as well. Now, iPhone 4 will be shipped running on iOS 4. So, it can be deduced that unlocking iPhone 4 means that iOS 4 (Baseband 05.13.04) should be unlocked.

We already know that jailbreak iOS 4 3GS and jailbreak iOS 4 3G have been successful which shows that iOS 4 will also be jailbroken on iPhone 4 probably within hours. Regarding iOS 4 baseband unlock, we also have some good news from iPhone Dev Team. Their prominent team member, MuscleNerd, had confirmed the expected release date of iPhone 3.1.3 unlock (05.12.01) and iOS 4 unlock. A newer version of ultrasn0w will unlock these firmware.

You might be wondering will there be a solution to unlock iPhone 4 by GeoHot, the wonder kid. He has been pretty calm on any developments since we came to know about limera1n. It is anticipated that his next tool will jailbreak iOS 4 on iPhone and iPod Touch. We predict that limera1n jailbreak will be accompanied with limesn0w to unlock iOS 4. Thus limesn0w will be able to unlock iPhone 4 being operated on iOS 4.

We have to wait till end of june when ultrans0w or limesn0w will be released to unlock iOS 4 on iPhone 4.
