What is Unlocking?

Definition of Unlocking:
Unlocking is the removal of SIM restrictions on the modem, allowing the use of the iPhone on any carrier. There are 2 types of iPhone unlocks:

• Software unlock: the iPhone is unlocked by a software unlock.

• Modification have to be made to the actual hardware to unlock the phone.

Software unlocks are safer because they do not modify your device and can easily be reverted back.


Why Unlock Your iPhone
The main reason to unlock your iPhone is if you want to use it with a different service provider (ie T-Mobile). An unlocked iPhone also has a better re-sell value.


Why Not Unlock Your iPhone
If you’re good with your phone carrier and will not use your iPhone internationally, there is absolutely no reason for you to unlock your iPhone.


How Do I Unlock My iPhone?
Before unlocking your iPhone, you will have to jailbreak it. The unlock can either be done from a computer, or directly from the iPhone.


What If Something Goes Wrong?
If something goes wrong, you can always restore your iPhone to factory settings.


In Short…
I case you’re still not really sure you understand the difference between jailbreaking and unlocking, let me put it in very simple words. Jailbreaking an iPhone means that 3rd party applications can be installed on it (ie. apps from other developers than Apple). Unlocking an iPhone means that any SIM card can be used on it.
