Most of the phones that are for sale in the United States are locked. Locked means that the phone can only use the standard network provided by the manufacturer. For the Apple iPhone 4G, Apple had restricted the American users to use the AT & T. If you live in Great Britain, you have to use the O2 network.
Many people want to unlock iPhone 4G because they want to call their friends with a cheaper network. The AT & T charges an expensive data rate and is not economical for people that regularly make phone calls. A lot of users have sought to cheaper alternatives because they are more affordable. Users that successfully unlock iPhone 4G can use other GSM carrier. If you want to use the SIM card, make sure you use the GSM compatible Sim card.
In addition, you will be able to use multiple phone numbers. To switch to a different phone number, you simply plug in the sim card into your phone. After unlocking the iphone, you will still be able to call via the AT & T network. Unlocking the iphone will not prevent any component from not functioning properly.

Question by shelly: Can I get ANY service if I get an “unlocked” iphone?
I’ve been wanting the iphone FOREVERRRR, but I have verizon. I’ve been told that I can get an “unlocked iphone” and use it for any service. Now, I’m not just talking about the apps, video, music, etc., I’m talking about using all of that, including using it as a phone. If it’s possible, is the service as reliable as using any phone on verizon (or tmobile, etc) THANK YOU!

You can tell it to activate the iPhone or not, disable the partition wipe, customize the root partition size, (pre)install custom packages, customize boot logos, or whether to preload Bootneuter for unlocking. After customization, you click the giant “Build” button which builds a custom firmware with all the customizations defined. You then have to restore this custom firmware to your iPhone through iTunes. This invovles putting the iPhone in DFU mode. The tool does a decent job of guiding through the process of holding the right buttons at the right time. Once this is done, the hard part is over! Just wait until the phone boots, runs the …
