What is Factory Unlocked on an iPhone?

I'm buying an iPhone off ebay and want to know what factory unlocked means. I'm getting the straight talk plan at walmart and am wondering if the iPhone will work with that carrier.

This means the SIM card module on the phone is unlocked and useable with any carrier.

You can use a factory unlocked iphone on any Network Worldwide. Moreover there's no fear of your phone getting locked again when you update your phone's software to the latest version.

Factory unlocked means the iPhone does not come with the usual 1 carrier restriction like most phones do. As long as its a GSM carrier, yes it will work just fine.

Factory unlock means you can use your phone to whatever carrier you prefer. To know more about Factory Unlock check this out: http://jailbreakhome.com/. I was able to know more about Factory Unlock on that site.

  • 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.
