This might save the user money over the long run but leaves AT&T.

How to Unlock iPhone 4:

If you decide to unlock iPhone 4, you need jailbreak it first. The unlock can either be done from a computer, or directly from the iPhone. We suggest you choose the safe and free unlock tool from Dev Team to unlock your iPhone 4. If something goes wrong, you can always restore your iPhone to factory settings.

Benefits of unlocking iPhone 4:

Once you've unlocked your iPhone, you'll be able to use it on any network, as long as its compatible with the iPhone's simcard system. The biggest iPhone 4 problem is AT&T. Most network problems related to its tendency to drop calls -- many are justifiably wary of purchasing a phone tied to a problematic network. The unlocked iPhone 4 gives users access to other network like T-Mobile's GSM network, which works overseas and may be more robust in your area. So, you can make calls on a non-approved carrier by Apple, and if you travel internationally, you can use a different sim card also.

The different between jailbreak and unlock:

Jailbreaking iPhone 4 means giving a user access to otherwise locked OS files on your iPhone 4, that would change the root of the directory tree. Typically, it allows your iPhone 4 to run third-party unsigned code by Apple, and customize the background of your home screen and change the look of your icons and menu colors.

If you have an approved carrier, you only need to jailbreak your phone, not unlock your phone. Some jailbreak tool don't unlock your iDevice in order for it to be able to make calls on a non-approved carrier, they just hack/patch your device in order to add the third applications to your iDevice, so pay attention at the jailbreaking procedure and tutorials.
