Hello guys, I have an iphone 4 I am aTT customer. I used to have iphone 2G. I used to unlock now I dont use it. Now my os is the latest , 4.2.1 . I will go to another country for 1 month . I need to use my phone there. I found this website, they say money back guaranteed. did anybody tried this website? Unlock iPhone 4 4.1 / 4.2.1, 3G, 3Gs. Jailbreak / iPhone Unlock Software 4G
I don't think it's true and I doubt it. They're claiming it will unlock 4.2.1 or 4.1 and there's no unlock for those version baseband; and also you don't unlock 4.2.1/4.1 or the OS, you unlock the baseband for.
And it also says about jailbraking so I'm guessing they just using the tools created by the dev teams which are totally free.
