What is the Definition of an Unlocked iPhone?

An iPhone that is unlocked.

An unlocked iPhone is an iPhone that has the ability to be used with any carrier and not locked to one carrier.

A phone that will be able to accept any type of sim, being orange, tesco, vodaphone… So on

An iPhone that isn't tied up to a specific carrier.

The iPhone is SIM locked, meaning that it can only be used on AT&T and Verizon's networks in the US, a move that has caused substantial criticism from some users.

However, a number of third-party programmers have found ways to unlock the iPhone through both hardware and software. Few of these techniques have been widely released and the iPhone seems only to work on T-Mobile and AT&T for now.

  • Will an unlocked iphone 4S work for tmobile if it isn't factory unlocked? I want to get an iPhone 4S and my friend has the iPhone 4 unlocked but i'm worried that if i get it non-factory unlocked it won't work. My uncle tried to do it a couple of months ago and apple said that if it was factory unlocked every time the phone shut off or died it would reset. I was just wondering if the same thing would happen if it wasn't factory unlocked? So if I get it unlocked everytime it will shut off it will reset? That is what i'm worried about.
  • Will a bad screen affect the quality and high definition of the iphone5s? I cracked my iphone 5s screen and i'm planning to repair it. My question is, will bad quality screen affect the hd in the phone or is it just durability difference?
  • Why do I look terrible in High definition cameras? I look better in Iphone/not very good quality cameras than HD cameras. Why is that? Is their anything that will make me look better in front of them?
  • Why are there Chinese characters with Unihan code but do not have a definition? Sometimes I may randomly draw a Chinese character out on the iphone and it matches an existing character, but why is it that when I search it, it doesn't have a definition. I try looking in the unicode databases but still there's no definition and sometimes no pronunciation. Is it because the character's are too old that there's no definition or what. Why would they have a character without meaning?
