If the carrier for your iPhone is the carrier your iPhone is carrier locked with unlocks iPhones, you need to contact your carrier to request your iPhone be unlocked. This can be initiated by the carrier the iPhone was sold as carrier locked with when new only. MacBook Pro 15, Mac OS X (10.6.7), iPod w/Video 30GB, iPhone 4 32GB

Call the carrier you purchased the iPhone from or on a plan with. Give them your IMEI number (Settings > General > About) and they will unlock it.
Once they have you need to restore the iPhone to bring the new information to the phone from the server.

Do not waste money on Virtual downloads that claim they can unlock your iPhone 4 or those sim cards that make the same claim, they can't. You MUST go to the original carrier for the unlock.

My carrier AT&t unlocked my iPhone for me, and they were so nice about it too. I would highly recommend contacting your carrier. It works perfectly with T-Mobile no glitches, nothing, everything works. I would like to jailbreak it though to get Cydia, but Iam scared, I don't want to screw my unlock up. Any advice!

You should be scared.
Hacking an iPhone removes all built-in security making your iPhone as insecure as android garbage opening your iPhone up to malware including your personal and financial info being harvested.
