Read alot BUt-Unlock v4.1 B02.10.04

[qarliv]

I'm not easily opening a new thread on an apparently trivial question. It is just the fact that after all excellent guides I've read, it is still not clear to me if I can unlock my iPhone.

It is AT&T iPhone 4 with ver. 4.1 (8B1117) and firmware 02.10.04.
I would like to jailbrake the phone and unlock it. I need a 1, 2, 3.. guide to which tools to use?

I did a research in the forum but got confused, I am not sure which steps to take for this version to jailbreak and if it is POSSIBLE to unlock it by software?

Thanks,

To jailbreak it, either use GreenPoison or Redsn0w.

To unlock it, you're going to need a Gevey Turbo sim.

No software unlock.
You can jb though.

Got you

Thanks.
Is it possible to change the baseband such that it can be unlock? Is this procedure safe?

No, you cannot change the bb on an i4.
