There are 2 ways to unlock the phone. The first way is the phone needs to be in service with AT&T and then you can call them up and have them unlock it for you for free.

The 2nd way is to use a 3rd party unlocker to unlock it, for a fee. There are plenty of unlockers on the net, do a google search for them.

There's something called GEVEY, they sell sim card slots that can unlock your i phone but you have to check with them if it can work with your phone.

They are not scammers and yes it does work i have one myself.

Yes you can unlock iPhone 4. You can unlock it yourself by following careful tutorials and how to. What I did to unlock my phone in a safe method is ask for a help from those who are offering iPhone unlocking service.www.attiphoneunlock.net might help you.

Jailbreak (software unlock) or find a provider on the internet who will unlock it.AT&T may also do it if it is out of contract and you are the original owner.
