Unlock or jailbreak?
I hear those terms a lot, but what's the difference between them? I'm guessing one has to do with the carrier and one the operating system. Is either legal?

What’s different between iPhone unlock and iPhone jailbreak?
http://www.makeuseof.com/answers/iphone-unlock-iphone-jailbreak/
"There’s actually a significant difference between an iPhone jailbreak and unlock. The jailbreak deals with the softwares and apps on the iPhone, while unlocking the phone lets users use other wireless networks (SIM) on the phone.
1. Jailbreaking
Jailbreaking usually pertains to softwares and apps on the iPhone / any other phone which you jailbreak. By jailbreaking, you can actually run softwares and apps that are usually not allowed to run. You can install these apps because the jailbreak affects the firmware of the iPhone or the iDevice. This lets you install apps that are not on the App Store. This means, lots of control and freedom over what you download and what you install in your iPhone.
Jailbreak lets you modify the resources on your iPhone. That way, you get to install softwares like Cydia which provide thousands of free and jailbroken apps that can be installed on the iPhone. The jailbreak actually is best for installing apps which are not approved by Apple. This is called unsigned code. These apps might also let you modify certain settings on the hardware like for instance, iPhone 3GS video recording, and even unlocking the phone.
2. UnlockingUnlocking is a totally different thing. It has a sole purpose – to let you use different carriers (SIM or network providers) on your iPhone. Technically, the iPhone can be run either on AT&T or on Verizon and that is dependent on which provider you go with. However, if you want to use the iPhone on any other service provider, you cannot do that without unlocking your phone. This applies to all mobile phones actually. Unlocking a phone is either through software or through hardware change. While meddling with the hardware might be risky, software unlock is most-followed method, especially in the case of iPhone.
Jailbreak and unlock have been declared legal to a large extent of late. This however does not mean the user policy of the providers have changed. It only means you cannot be sued for unlocking or jailbreaking a phone anymore. It just means you lose the warranty or support through jailbreak and unlock.+"

Jailbreaking is analogous to rooting an Android device. In the US it is legal to jailbreak your iPhone, iPad, etc., although it may violate contractual terms and void your warranty. The primary benefit for most people is that it let's you make your own decisions as to which apps you want instead of being forced to rely on Apple approved apps.
Unlocking is simply allowing an iPhone, iPad, etc. to be "unlocked" for use on a different carrier network that the one for which it was initially sold/set up. Basically, it allows you to avoid being held hostage by a carrier, and lets you change carriers without the need to replace your perfectly good device with a new one. This has been legal for years, but according to those more knowledgeable than myself here at IT World, it is about to become illegal on January 26. I personally think this is an absurd change that skews the balance of power further in the favor of carriers (as if it wasn't skewed enough already). The counter argument is that it prevents purchase of phones and unlocking them for sale at a price which undercuts what carriers are selling them for.

Unlocking a phone is completely different than Jailbreaking.
Jailbreaking is the process of removing limitations/restrictions so that 3rd party applications can be installed.
Unlocking a mobile phone is a procedure to remove any SIM/Network restrictions set on the phone by either the manufacturer of the phone or by the mobile phone's service provider. After unlocking a mobile phone, you can still use it with its existing network or switch over to any other supported network.
