Here is a quick update for those who are waiting for iPhone 4 02.10.04 and 03.10.01 baseband unlock. According to the recent tweet by MuscleNerd, Ultrasn0w unlock for iPhone 4 with 02.10.04 or 03.10.01 baseband might get delayed for some more days or may be weeks. Earlier, MuscleNerd confirmed that he will not release unlock until Apple releases iOS 4.3 publicly. Now that Apple has released iOS 4.3, everyone was expecting the unlock within a week or two.
Sorry, there's no news on the i4 unlock for those who lost 01.59 (or never had it). It's taking longer than we wanted :(
For those who don't know, the baseband of iPhone 4 runs ThreadX which is a RTOS (Real-Time Operating System). Like most of RTOSes, ThreadX uses a multitasking kernel with advance scheduling, fast interrupt response and very good memory management. Definitely the kernel of such OSes are hard to crash and thats why Apple used ThreadX to run the baseband of iPhone 4.
Although iPhone 4 baseband is protected by ThreadX, still Shrief Hashim found an exploit which can unlock both of these basebands. Sherif Hashim, himself confirmed that his exploit can unlock iPhone 4 02.10.04 and 03.10.01 baseband. So, all those who are waiting for the unlock should never get disheartened by MuscleNerd's tweet. Hopefully, we will get unlock within a month now.Contact Us for News Tips, Corrections and Feedback
