Need help... unlocking.

[mich300190]

I have a iphone 3gs which I have managed to jailbreak pretty easily for someone who is new to all this.

Now the problem I have is unlocking it to any network, the current IOS and baseband is...

IOS - 4.3.3
Baseband - 05.16.02

Now I haven't done this before so just looking for a bit of guidance to help me along the way, thanks in advance for any help given.

Use a Gevey Sim so that your iPhone can become openline to any cellular network
