Possibility of SIM unlock on iOS6.1 (iPhone 4)

Hi, its been almost two years since the last post, haha.....
And here it goes.
[This post is a kind of experiment! I wrote a post about the same stuff in Japanese and the access to this one is quite high for me, so I want to see how it goes in English (since the number of English speakers is so much more than that of Japanese).]

So, about three weeks ago the JB tool called "evasi0n" has released which allows us to JB iOS6.x devices. At the same time, there is a software called "Ultrasn0w Fixer 6.1" in Cydia store. Also in some auction sites, there are a lot of products saying "SIM unlocked iPhone 4 with iOS6.1 BB01.59.00." Given the situation, I thought iPhone 4 with iOS6.1 (with preserved BB 01.59.00) could be SIM unlocked by ultrasn0w and I did an experiment on my own iPhone 4 on the 13th of February, 2013.

The result was... negative.
I have an iPhone 4 iOS4.0.2 with BB01.59.00 which is jailbroken. So what I did was jailbreak this device with Sn0wBreeze 2.9.9 and produced CFW so that I can update iOS4.0.2 to iOS6.1 preserving BB01.59.00. Then, I applied ultrasn0w 1.2.8 and ultrasn0w fixer for 6.1.

But it did not work at all. Some people on JailbreakQA also said it did not work on iOS6.1 on iPhone 4 (Although Some Japanese blogers reported iOS6.1 on iPhone 3GS was successfully SIM unlocked).

So, that's it. Mmm, single post without any other iOS related posts does not seem reliable, does it? :P
Well, let me try to post some more in the future... They will be basically just translation of my Japanese blog.

  3. Thanks for your nice information. Now a days there are lot of methods available to unlock an iphone4 such as hardware,software,sam,,remote unlock method and etc.But according to my opinion remote unlock method is the best and easy method to unlock an iphone4. Because other methods contains lot of steps. It is not comfortable for me. So i have chosen remote unlock method and i got service from this site Theunlockarena.com then i unlocked my iphone4 easily.
