iPhone downgrade 5.0.1 to 4.3.5 help PLZ!

[striderz1]

Hi everyone, I wanted to ask you all for your expertise, tried looking on the forums and didnt find anything similar to the issue I am facing..

So i upgraded my iphone to 5.0.1 while preserving my 03.10.01 baseband

Now i need to unlock this phone and found out that only option I have now is Gevey sim, which i now have bought. But on their website it states that for ios 5.0.1 you should have 04.10.01 bb.

So my question is how do I do that, what steps are necessary for me to successfully do that? I tried install 4.3.5 but itunes says that i cannot with this iphone anymore.

Please any help you guys can provide will be much appreciated. thanks!

As far as I know, it will work fine with 5.0.1 and 3.10.xx combination
Download FuriousMod from Cydia to assist using the sim interposer

You dont need the 04.10.01 bb
The one you have saved now will work fine.

Thank you for the replies

The only reason I asked is because I tried using my friend's gevey with the 03.10.01 baseband and it wouldn't work, though i didnt install furiousmod, and i think his gevey was a fake.

Do you guys think those factors would cause it not to unlock?

Get FuriousMod and try your sim interposer
Read info at the Applenberry website
What have you got to lose trying it ?

Depends on the gevey.
There's tons of junk fake chips out there that dont even work at all. I was trying one on a friends phone the other day for hours and couldnt get it to work. It would connect for a few minutes and then give errors like invalid sim or no service. What a pain.
If its a genuine gevey it wont have a problem unlocking that baseband version on that firmware.

Thanks alot for your reply!

I was in a hard situation, since I had to travel overseas for work and couldnt get genuine gevey there, and the fakes werent working. First thing i did before coming back, was ordered the gevey, I just flew in yest and was wondering about my options, and if the gevey doesnt work i'll have to try to sell this one and buy a unlocked one all within 6 days before i leave again for about 2 months :S

Quick question would I be able to check if it is working with tmobile with their pay-as-you-go sim?
