iPhone Can't unlock iPhone 4 after updating to 5.1.1

[PhucPaul]

I recently updated my iPhone 4 to Version 5.1.1 from 4.3.3.

I did preserve my baseband and I am at 4.10.01.

My iPhone is unlocked via Gevey SIM, but after updating to 5.1.1, I am getting some complication on unlocking it for T-Mobile.

Tips will be appreciated, thanks!

Applenberry has support tutorials on their website.

Try installing FuriousMod in cydia.

Thank you, I got it.

Now I have one more question, should I use "Rocky Racoon" or "FuriousMod" to untether my jailbroken iPhone?

What?!

Do you even know what FuriousMod is? I did a minute google-ing and it's not for untether JB.

FuriousMod will not untether your jailbreak.
But it will help with the use of the Gevey sim.
