Well it's running 4.0, can't I downgrade to 3.1.2?
You didnt say if its a 3G or 3GS.
Either way you wont be able to unlock it even if you can downgrade the firmware.
If you have a very early 3G model you might be able to try fuzzyband but chances are slim.
But are you positive that it is impossible for me to unlock it?
How come I see tutorials on the web to unlock a 3GS under 3.1.3?

I'm pretty sure that tutorial refers to a way to upgrade to 3.1.3 without updating the baseband. If you update through iTunes, it will automatically update the baseband and you will not be able to unlock (currently).
So I can downgrade to 3.1.3 using xcode, anyway I could use one of those modified ipsw's that are jailbroken to downgrade?
3GS.

I've got to ask. How come you know nothing about what can be unlocked but are running around with a 4.0 iphone?
The internet... Can provide you with walkthroughs for all manner of things from pirating MS Office to building a bomb. Cannot provide you with common sense.![]()
On eBay, phones sell more if they are unlocked, is it possible that I could unlock it myself?
I have a related question to this. Is it safe to go to mall technicians just to unlock you iPhone? I am not really sure if it's safe because some of them might think that it is stolen.
