How to Sim unlock an Iphone 5c?

I traded my Samsung Galaxy Note II for an Iphone 5c on craigslist. The Iphone that the man gave me has Sim lock on it. I went to AT&T, and they said they couldn't activate an account for me until it got unlocked. Any ideas on how to unlock the Sim without having to purchase something?

When I delete voicemail from my iPhone 5, they do not delete from the system?

On my iPhone 5, I get the notice that comes up saying Voicemail is 92% full or 95% full or then even 100% full. So on my iPhone, I delete all the voicemails, they go to a Deleted Messages folder, I go in and hit Clear All and they are gone. Sort of. I don't see them on my iPhone, yet my voicemail box is still 100% full. Now I have to call my own number for voicemail and delete each one individually by hitting 7. What a pain my ***! Please help me, what am I missing. How else can I delete emails from the system?

Will apple repair my iphone 4 screen glass?

I dropped my iPhone 4 and the glass cracked on the front, it's not the actual screen, just the glass that covers it, everything else works fine, I read on some Apple forums that if you take your phone to an Apple store, they repair it for free, is this true? Has anyone had to pay for Apple to repair their screen, if so, how much?

Why do some functions of my computer stop working after a while?

For some strange reason, certain functions of various programs cease to function after using my laptop for about an hour. For example, when my computer is freshly booted and I open up iTunes, everything works fine. At some point, however, I will not be able to drag music to or from the program, or put music onto my iPhone. The file will simply not budge.

Also, I have various sounds attached to certain functions of the computer (ie.minimize window, low battery alert, etc.). Sooner or later they will simply stop, after which there's NO sound coming from the speakers. Music will not play in iTunes, the play bar will simply freeze and the program will ultimately lock up.

Another example of this problem I've noticed is in Photoshop CS5. Functions of the program will just stop working. Both a manual File>Save and Ctrl+S will bring up a save window, but it will not actually save the file. Sometimes File>Save and Ctrl+S won't work at all. At this point, you can't even open new images. Once again, the dragging feature is inoperable.

All of these issues seem to be fixed by resetting the computer, but it's only a matter of time before they happen again. And again. I can't tell you how much of a HUGE letdown it is to be working on important design files and suddenly I'm not able to save them.

Please note that the above problems are only the ones that I have noticed most frequently and that have interfered with my general use of the computer. The "disabled dragging" is the most noticeable issue.

What is going on here!

I plan on buy an iphone and I want to know if this one is a good one?

I want to purchase a iphone 4s 5th generation, but what does that mean? I seen another phone that said iphone 4s fourth generation, but it cost more than the 5th.why? Which is better?

I know there's a new iphone out but what is the difference and if you have a phone with 8 gb can you buy more or would you have to purchase a phone that has more gb.

Also if a phone is unlock does that mean you can get a plan from any cell phone company?

sorry I know nothing about phones.dial text and talk is all I know.

What's this iPhone game called?

I used to play it all the time. It's a circular planet thing and you start off with a few people and as you gain points or whatever, you get more people and the world gets bigger. There's also like a God. And there's rain clouds and you can deform the world to make mountains or lakes.
