Verizon iphones can't be unlocked?

So verizon iphones can't be unlocked?

Yes they can be unlocked, but only the Verizon phones that have world phone capability, which means they also include a SIM slot and GSM radios. Such phones are the iPhone 4S, iPhone 5, Droid Incredible 2, and some others. Although in most cases, they will only unlock to carriers outside of the USA, and not to other domestic carriers (such as AT&T or T-Mobile). The only exception I know of is the Verizon iPhone 5, which is actually unlocked for both international AND domestic use OUT OF THE BOX.

IPhone which is locked at Verizon can be unlocked. I have a friend who unlock her iPhone at attiphoneunlock.net. She just sent her IMEI code and wait for a day and her iPhone is unlocked for good.
